|Did either of these change by more than 5%?<br />
|Yes. <br><br />

|At the SURFACE, list all species that changed by 10% or more:<br />
|NO<sub>x</sub>, PAN, N<sub>2</sub>O<sub>5</sub>, HNO<sub>4</sub>, O<sub>x</sub>, Alk4, isoprene, H<sub>2</sub>O<sub>2</sub>, ALD2, CH<sub>2</sub>O, DMS, NIT, MP, MVK, MACR, PMN, PPN, SO<sub>2</sub>, and SO<sub>4</sub>. <br />
|-<br />
|Comments on SURFACE differences: <br />
|NO<sub>x</sub> (but only over the ocean, where concentrations were small), surface PAN over oceans, N2O5 over oceans, HNO4 over oceans, Ox over oceans at latitudes above 45N (but global means are <10% consistent with v8-02-02), Alk4 increases over oceans at lats above 45N (consistent with decreases in OH and Ox), isoprene increases exceed 10% in remote regions (in response to OH decreases), H2O2 decreases exceed 10% in remote regions, ALD2 and CH2O decreases exceed 10% in remote regions (dominant reaction partners with Br producing HBr), DMS increases exceed 10% (mostly in N extratropics, tracking decreased OH), and NIT and MP in the remote northern extratropics. Also, SO2 increases and SO4 decreases by >10% in the Arctic due to lower OH. The MVK and MACR increases are in response to lower OH. PMN and PPN decreases are >10% in remote regions due to NOx decreases.<br />
|<br />
|-<br />
|At 500 hPa, list all species that changed by 10% or more:<br />
|NO<sub>x</sub> (extratropics), N<sub>2</sub>O<sub>5</sub>, NH3, HNO<sub>4</sub>, isoprene, ALD2 in Southern extratropics only (low concentrations), PMN, PRPE, DMS, NIT, SO<sub>2</sub>.<br />
|-<br />
|Comments on 500 hPa differences:<br />
|NIT changes are just noise where concentrations are near 0, NH3 increased over the antarctic where concentrations are near 0. N<sub>2</sub>O<sub>5</sub> decreases in remote regions globally but also increases North of 80N, which is not seen in the surface simulation; this is happening because concentrations of N<sub>2</sub>O<sub>5</sub> are near 0 there. Changes in the other listed species are consistent with explanations given for the surface difference plots.<br />
|-<br />
|In the ZONAL MEAN differences, list all species that changed by 10% or more: <br />
|NOx in the extratropics (low concentrations), Ox in the Arctic PBL, PAN in the PBL and remote FT (southern extratropics), Alk4 in the northern hemisphere (due to OH decrease), global isoprene (due to OH decrease), H2O2 mostly in the northern hemisphere PBL, PPN in the PBL and remote FT (southern extratropics), MP increases in the Arctic PBL due to lower OH. Other species that change >10% in the zonal mean due so where there are near-0 starting concentrations. <br />

|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />

|Some related to changes in surface; a bit puzzled by changes to a few species like NH3, NIT, and ISOP (one grid box over the Amazon), but likely related to changes to chemistry at surface caused by regridding change (ISOP) or in regions with very low concentratiomns (eg NIT) <br />

|I think the changes in ISOP, MVK, etc are related to changes in chemistry caused by changes in regridding, but am a bit puzzled by NIT and NH3 changes.<br />
|-<br />

|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small.

|-<br />
|Comments on ZONAL MEAN differences:<br />
|ISOP shows % differences of about ~5% in places where concentrations are already very low. [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]], we attribute these changes to the numerical differences caused by regridding leaf area index data from 0.5&deg; x 0.5&deg; native resolution (instead of from 1&deg; x 1&deg;, as was done in the past).<br />
<br />
Differences in NH3 and NIT are attributed to the [[ISORROPIA_II#Persistence_of_problem|Numerical noise issue in ISORROPIA II]].<br />

|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|Comments on SURFACE differences: <br />
|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

|There are widespread increases in anthropogenic emissions of C2H6 by as much as 100%. Decreases of up to 50% occur in some regions, primarily in regions where C2H6 anthropogenic emissions are low in the first place. Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

|-<br />
|Comments on 500 hPa differences:<br />

|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|-<br />
|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|Comments on ZONAL MEAN differences:<br />
| Most of the effects are concentrated near the surface, where the sea salt burden is highest.<br />
|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv).

|-<br />
|Comments on SURFACE differences: <br />
|NO<sub>x</sub> (but only over the ocean, where concentrations were small), surface PAN over oceans, N2O5 over oceans, HNO4 over oceans, Ox over oceans at latitudes above 45N (but global means are <10% consistent with v8-02-02), Alk4 increases over oceans at lats above 45N (consistent with decreases in OH and Ox), isoprene increases exceed 10% in remote regions (in response to OH decreases), H2O2 decreases exceed 10% in remote regions, ALD2 and CH2O decreases exceed 10% in remote regions (dominant reaction partners with Br producing HBr), DMS increases exceed 10% (mostly in N extratropics, tracking decreased OH), and NIT and MP in the remote northern extratropics. Also, SO2 increases and SO4 decreases by >10% in the Arctic due to lower OH. The MVK and MACR increases are in response to lower OH. PMN and PPN decreases are >10% in remote regions due to NOx decreases.<br />
|<br />

|At 500 hPa, list all species that changed by 10% or more:<br />
|NO<sub>x</sub> (extratropics), N<sub>2</sub>O<sub>5</sub>, NH3, HNO<sub>4</sub>, isoprene, ALD2 in Southern extratropics only (low concentrations), PMN, PRPE, DMS, NIT, SO<sub>2</sub>.<br />
|-<br />
|Comments on 500 hPa differences:<br />
|NIT changes are just noise where concentrations are near 0, NH3 increased over the antarctic where concentrations are near 0. N<sub>2</sub>O<sub>5</sub> decreases in remote regions globally but also increases North of 80N, which is not seen in the surface simulation; this is happening because concentrations of N<sub>2</sub>O<sub>5</sub> are near 0 there. Changes in the other listed species are consistent with explanations given for the surface difference plots.<br />

|In the ZONAL MEAN differences, list all species that changed by 10% or more: <br />
|NOx in the extratropics (low concentrations), Ox in the Arctic PBL, PAN in the PBL and remote FT (southern extratropics), Alk4 in the northern hemisphere (due to OH decrease), global isoprene (due to OH decrease), H2O2 mostly in the northern hemisphere PBL, PPN in the PBL and remote FT (southern extratropics), MP increases in the Arctic PBL due to lower OH.

|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small.

|Differences are seen in ISOP in locations where concentrations are already very low (i.e. over oceans). MVK and MACR differences are presumably tied ot to the differences in ISOP. [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]], we attribute these changes to the numerical differences caused by regridding leaf area index data from 0.5&deg; x 0.5&deg; native resolution (instead of from 1&deg; x 1&deg;, as was done in the past).<br />

|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

|There are widespread increases in anthropogenic emissions of C2H6 by as much as 100%. Decreases of up to 50% occur in some regions, primarily in regions where C2H6 anthropogenic emissions are low in the first place. Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

NOTE: The kludge implemented to [[Wet_deposition#Anomalous PRECTOT values on 22 July 2010|prevent crashes in wetdep when encountering anomalously low PRECTOT values]] causes very small (mostly on the order of 0.0001 ppbv) changes in tracer concentration, as seen in [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.differences.dyn_range.pdf this dynamic range difference plot] with ISORROPIA turned off. The kludge is still an improvement to the code because the fraction of the precipitating box should always be between 0 and 1.<br />

|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|-<br />
|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv).

|-<br />
|Comments on SURFACE differences: <br />
|NO<sub>x</sub> (but only over the ocean, where concentrations were small), surface PAN over oceans, N2O5 over oceans, HNO4 over oceans, Ox over oceans at latitudes above 45N (but global means are <10% consistent with v8-02-02), Alk4 increases over oceans at lats above 45N (consistent with decreases in OH and Ox), isoprene increases exceed 10% in remote regions (in response to OH decreases), H2O2 decreases exceed 10% in remote regions, ALD2 and CH2O decreases exceed 10% in remote regions (dominant reaction partners with Br producing HBr), DMS increases exceed 10% (mostly in N extratropics, tracking decreased OH), and NIT and MP in the remote northern extratropics. Also, SO2 increases and SO4 decreases by >10% in the Arctic due to lower OH. The MVK and MACR increases are in response to lower OH. PMN and PPN decreases are >10% in remote regions due to NOx decreases.<br />
|<br />
|-<br />
|At 500 hPa, list all species that changed by 10% or more:<br />
|NO<sub>x</sub> (extratropics), N<sub>2</sub>O<sub>5</sub>, NH3, HNO<sub>4</sub>, isoprene, ALD2 in Southern extratropics only (low concentrations), PMN, PRPE, DMS, NIT, SO<sub>2</sub>.<br />
|-<br />
|Comments on 500 hPa differences:<br />
|NIT changes are just noise where concentrations are near 0, NH3 increased over the antarctic where concentrations are near 0. N<sub>2</sub>O<sub>5</sub> decreases in remote regions globally but also increases North of 80N, which is not seen in the surface simulation; this is happening because concentrations of N2O5 are near 0 there. Changes in the other listed species are consistent with explanations given for the surface difference plots.<br />

|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small. Other species (ie HNO3, NOx) with large differences generally have a grid box with positive change next to box with similar negative change. This is due to slight shifts in location of some emissions under new regrid algorithm.<br />

|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

|-<br />
|Comments on EMISSION RATIO differences:<br />
|There are widespread increases in anthropogenic emissions of C2H6 by as much as 100%. Decreases of up to 50% occur in some regions, primarily in regions where C2H6 anthropogenic emissions are low in the first place. Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

NOTE: The kludge implemented to [[Wet_deposition#Anomalous PRECTOT values on 22 July 2010|prevent crashes in wetdep when encountering anomalously low PRECTOT values]] causes very small (mostly on the order of 0.0001 ppbv) changes in tracer concentration, as seen in [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.differences.dyn_range.pdf this dynamic range difference plot] with ISORROPIA turned off. The kludge is still an improvement to the code because the fraction of the precipitating box should always be between 0 and 1.<br />

|-<br />
|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

Over continental regions, the largest changes are away from terrestrial acetone sources. There are smaller relative changes over the main continental emission regions. PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv).

Also, SO2 increases and SO4 decreases by >10% in the Arctic due to lower OH. The MVK and MACR increases are in response to lower OH. PMN and PPN decreases are >10% in remote regions due to NOx decreases.<br />

|At 500 hPa, list all species that changed by 10% or more:<br />
|NO<sub>x</sub> (extratropics), N<sub>2</sub>O<sub>5</sub>, NH3, HNO<sub>4</sub>, isoprene, ALD2 in Southern extratropics only (low concentrations), PMN, PRPE, DMS, NIT, SO<sub>2</sub>.<br />
|-<br />
|Comments on 500 hPa differences:<br />
|NIT looks like noise probably due to low beginning concentrations, NH3 increases in the antarctic where concentrations are low likely since OH decreased. N<sub>2</sub>O<sub>5</sub> decreases in remote regions globally but also increases North of 80N, which is not seen in the surface simulation (possibly because the concentrations of N2O5 are low to begin with there, but this is being looked into now). Changes in the other listed species are consistent with explanations given for the surface difference plots.<br />

|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small.

|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

NOTE: The kludge implemented to [[Wet_deposition#Anomalous PRECTOT values on 22 July 2010|prevent crashes in wetdep when encountering anomalously low PRECTOT values]] causes very small (mostly on the order of 0.0001 ppbv) changes in tracer concentration, as seen in [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.differences.dyn_range.pdf this dynamic range difference plot] with ISORROPIA turned off. The kludge is still an improvement to the code because the fraction of the precipitating box should always be between 0 and 1.<br />

|-<br />
|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

| Most of the effects are concentrated near the surface, where the sea salt burden is highest.<br />
|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

|-<br />
|Comments on SURFACE differences:<br />
|ACET generally decreases 10-50%, strongest decreases over the oceans due to elimination of the (incorrect) ocean source. Over continental regions, the largest changes are away from terrestrial acetone sources. There are smaller relative changes over the main continental emission regions. PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv). Weak decreases for R4N2 in a couple spots. <br />

|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small.

|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|Comments on SURFACE differences: <br />
|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

|To eliminate the effect from ISORROPIA, we re-ran 1-month benchmarks for v9-01-02f and v9-01-02g with ISORROPIA turned off. We have created [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.freq_distribution.pdf this frequency distribution histogram plot]. As you can see, both benchmarks have identical results (i.e. 100% of all grid boxes in the central bar of the histogram). <br />
<br />
<br />
NOTE: The kludge implemented to [[Wet_deposition#Anomalous PRECTOT values on 22 July 2010|prevent crashes in wetdep when encountering anomalously low PRECTOT values]] causes very small (mostly on the order of 0.0001 ppbv) changes in tracer concentration, as seen in [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.differences.dyn_range.pdf this dynamic range difference plot] with ISORROPIA turned off. The kludge is still an improvement to the code because the fraction of the precipitating box should always be between 0 and 1.<br />

|-<br />
|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

|Comments on SURFACE differences:<br />
|ACET generally decreases 10-50%, strongest decreases over the oceans due to elimination of the (incorrect) ocean source. Over continental regions, the largest changes are away from terrestrial acetone sources. There are smaller relative changes over the main continental emission regions. PAN decreases by 10-25% over most of the NH oceans, but the absolute differences are very small due to low surface PAN mixing ratios in these regions (< 30 pptv). Weak decreases for R4N2 in a couple spots. <br />

|Comments on SURFACE differences: <br />
|For most species, small numerical noise where concentrations are low cause large percent differences. Absolute differences are generally small. Other species (ie HNO3, NOx) with large differences generally have a grid box with positive change next to box with similar negative change. This is due to slight shifts in location of some emissions under new regrid algorithm.<br />

|Differences are seen in ISOP in locations where concentrations are already very low (i.e. over oceans). MVK and MACR differences are presumably tied ot to the differences in ISOP. [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]], we attribute these changes to the numerical differences caused by regridding leaf area index data from 0.5&deg; x 0.5&deg; native resolution (instead of from 1&deg; x 1&deg;, as was done in the past).<br />

|ISOP shows % differences of about ~5% in places where concentrations are already very low.

|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
|Biogenic ACET, Biogenic ISOP, Biogenic PRPE<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|Comments on SURFACE differences: <br />
|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

|There are widespread increases in anthropogenic emissions of C2H6 by as much as 100%. Decreases of up to 50% occur in some regions, primarily in regions where C2H6 anthropogenic emissions are low in the first place. Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

|To eliminate the effect from ISORROPIA, we re-ran 1-month benchmarks for v9-01-02f and v9-01-02g with ISORROPIA turned off. We have created [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.freq_distribution.pdf this frequency distribution histogram plot]. As you can see, both benchmarks have identical results (i.e. 100% of all grid boxes in the central bar of the histogram). <br />
<br />
<br />
NOTE: The kludge implemented to [[Wet_deposition#Anomalous PRECTOT values on 22 July 2010|prevent crashes in wetdep when encountering anomalously low PRECTOT values]] causes very small (mostly on the order of 0.0001 ppbv) changes in tracer concentration, as seen in [ftp://ftp.as.harvard.edu/pub/exchange/mpayer/1mo_quick_look/v9-01-03g/v9-01-03g-2.differences.dyn_range.pdf this dynamic range difference plot] with ISORROPIA turned off. The kludge is still an improvement to the code because the fraction of the precipitating box should always be between 0 and 1.<br />

|In original model, ship NOx was released as 10*O3 and 1*HNO3 molecules (continuously, day and night). Now we release a fraction of the NOx, and O3 and HNO3 produced.

|-<br />
|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

|Some related to changes in surface; a bit puzzled by changes to a few species like NH3, NIT, and ISOP (one grid box over the Amazon), but likely related to changes to chemistry at surface caused by regridding change (ISOP) or in regions with very low concentratiomns (eg NIT) <br />

|All of the above-mentioned species show differences, especially near coastlines. All of these species are computed by the [[MEGAN biogenic emissions]] module, which now takes in the leaf area indices regridded from 0.5&deg; x 0.5&deg;, [[Leaf area indices in GEOS-Chem#Using Olson 1992 land map|As described in this wiki post]]. We attribute the differences in these species to the numerical differences in the leaf area index data.<br />
|-<br />
|Additional or summary comments:<br />
|The updates added to v9-01-03j were made to primarily assist development of the [[Grid-independent GEOS-Chem]]. We needed to rewrite the leaf area index module in order to (1) remove obsolete ASCII data files that were prohibiting the grid-independent model from functioning efficiently, and (2) compute leaf area indices consistently by regridding them from the native resolution (in this case, 0.5&deg; x 0.5&deg;) instead of using leaf area index data at several different resolutions. Also, we have merged into the standard repository several updates from Mike Long that are necessary in order to have GEOS-Chem driven by the NASA/GEOS-5 GCM.<br />
<br />
We performed benchmark v9-01-03j with the [[Olson land map#Olson 1992 land map|Olson 1992 land map]] (which is the default in GEOS-Chem), and the [[MODIS leaf area indices]], both at 0.5&deg; x 0.5&deg; resolution. The updated LAI code introduced into v9-01-03j will eventually allow us to use higher resolution versions of both the Olson land map and the MODIS leaf area indices. This will be an important step that will facilitate GEOS-Chem nested-grid simulations 0.25&deg; x 0.25&deg;.<br />

|-<br />
|Comments on SURFACE differences: <br />
|<br />
Concentrations of C2H6 increase 10-100% globally, except in eastern North America and coastal China. Typically, regional emission inventories overwrite the global emissions inventories; however, in this update, the C2H6 anthropogenic emissions overwrite has been removed for [[Anthropogenic emissions#EPA.2FNEI05|EPA/NEI2005]], [[Anthropogenic emissions#Streets 2006|Streets]], and [[Anthropogenic emissions#EMEP|EMEP]] because anthropogenic emissions of C2H6 were found to be [[Anthropogenic emissions#Anthropogenic ethane emissions are too low|too low in these regional inventories]]. Aside from decreases over eastern North America and coastal China, the offline C2H6 emissions improve concentrations over the rest of the North American and Asian regions.<br />
<br />
Smaller increases in PAN (~10%) and ALD2 (10-60%) are expected with an increase in C2H6, as C2H6 is a source of these species.<br />

|-<br />
|Comments on EMISSION RATIO differences:<br />
|There are widespread increases in anthropogenic emissions of C2H6 by as much as 100%. Decreases of up to 50% occur in some regions, primarily in regions where C2H6 anthropogenic emissions are low in the first place. Overall, this is an improvement from using RETRO C2H6 anthropogenic emissions, which were found to be too low.<br />

|In original model, ship NOx was released as 10*O3 and 1*HNO3 molecules (continuously, day and night). Now we release a fraction of the NOx, and O3 and HNO3 produced. This explains large increase in NOx, as no ship NOx was present before this update. Other species are influenced by changes in O3 (and consequently OH). <br />

|-<br />
|Comments on ZONAL MEAN differences:<br />
|Changes in below-cloud scavenging reduces concentrations of coarse dust and coarse sea salt but increases other aerosol concentrations. Changes in in-cloud scavenging decrease concentrations of BCPO, dust and HNO3 especially at high altitudes. As a result, dust concentrations are decreased at all altitudes. BCPO concentrations tend to decrease at high altitude but increase at low altitude. Concentrations of other aerosols tend to increase at high altitude especially over the tropics and subtropics. This is because we suppress the in-cloud scavenging at low temperature during convective updrafts so as to be consistent with the parameterizations in large-scale precipitation. <br />

|-<br />
|Comments on SURFACE differences: <br />
| Concentrations of sea salt aerosols (SALA and SALC) increase in the tropics by ~50-100% and decrease at mid-high latitudes by 50-100% as expected from the implementation of the SST dependent sea salt source function.<br />
The impact on other species is largest for nitrogen and sulfur species that directly interact with sea salt. While the levels for some of these species change by factors of 1.5-2 over the tropical and high latitude oceans (HNO3, NIT, NITs, SO4s, NH3, NH4), their concentrations are very small in these remote regions, so the absolute changes are small. For example, HNO3 increases by more than a factor of 2 over the remote southern ocean, and decreases by a factor of 2 over the tropics. But the absolute changes are a few pptv at the surface.<br />

|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
| SALA, SALC<br />
|-<br />
|Comments on EMISSION RATIO differences:<br />
| As expected from the inclusion of a SST dependence in the sea salt source function, sea salt emissions for accumulation mode sea salt aerosols (SALA) increase by 30-80% in warm tropical regions, and decrease by ~50% over high-latitudes. Overall SALA emissions decrease by 23%. Global emission of coarse mode sea salt aerosols (SALC) increase by 70%, with the largest increases in the tropics. This is driven by both the SST dependence but also the expansion of the size distribution of sea salt from 0.5-4 to 0.5-8 microns.<br />

== Overview ==<br />
Bromine chemistry has been added as an option to run with SMVGEAR or KPP in v.8-03-01 as an extension to the standard model's full chemistry simulation. Important features include:<br />
<br />
1.) Add 10 bromine tracers: Br2, Br, BrO, HOBr, HBr, BrNO2, BrONO2, CHBr3, CH2Br2, and CH3Br<br />
2.) 4 source gases:<br />
- CH3Br: PBL concentrations are set to average CMDL measured concentrations prior to each chemistry step.<br />
- Very short lived (VSL) source gases:<br />
- CH2Br2 and CHBr3. These account for > 80% of the VSL organic bromine through the troposphere (WMO, 2007).<br />
- Emissions are taken from Q. Liang et al. [2010] + a seasonal scaling for CHBr3 at lat > 30N described in J. Parrella et al. [in prep.]<br />
- 429 Gg CHBr3 / yr; 62 Gg CH2Br2 / yr<br />
- Sea-salt debromination:<br />
- Largely follows Yang et al. [2005], treating the debromination as an emission of Br2, constrained to measured bromide depletion factors.<br />
- 1.4 Tg Br2 / yr using the Monahan sea-salt production function and coarse aerosol bin range of 0.5 - 10 um.<br />
3.) Wet and dry deposition for HBr, HOBr, and BrONO2.<br />
<br />
Code should be made available soon. This wiki page is under construction, but feel free to contact Justin Parrella (parrella@fas.harvard.edu) with any questions about the code.<br />
