|Comments on SURFACE differences: <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 500 hPa differences:<br />
|The significant decreases in DUST, BCPO and HNO3 are because of the in-cloud scavenging by snow. <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 />

|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 />

|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 />

|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 />

|-<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 />

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 />
|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 500 hPa differences:<br />
|The significant decreases in DUST, BCPO and HNO3 are because of the in-cloud scavenging by snow. <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 />

|Sort of makes sense. Changes are in regions that are NOx starved (South America) or cold (the loss from GLPAN will be greatest). Changes are small overall and almost always negative. The changes for DMS are relatively large (10-20% decrease)<br />
|-<br />
|At 500 hPa, list all species that changed by 10% or more:<br />
|ALK4, ISOP, MEK, MVK, MACR, PRPE (large changes in polar regions > 20%), DMS<br />
|-<br />
|Comments on 500 hPa differences:<br />
|Changes are generally bigger than at the surface (temperature dependence of GLPAN)<br />
|-<br />
|In the ZONAL MEAN differences, list all species that changed by 10% or more:<br />
|ISOP (but at high altitude and in polar regions), ALK4 in polar regions, MEK, MVK, MACR, PMN, PRPE<br />
|-<br />
|Comments on ZONAL MEAN differences:<br />
|Small changes overall (in an absolute sense). DMS has the largest change.<br />
|-<br />
|In the EMISSION RATIO maps, list all species that changed by 10% or more:<br />
|none <br />

<div>This page describes the various ship emissions inventories that have been implemented in GEOS-Chem.<br />
<br />
== Overview ==<br />
<br />
At present there are several different ship emissions options in GEOS-Chem.<br />
<br />
;ARCTAS: The ARCTAS pre-mission ship SO2 emissions from David Streets. [''Eyring et al'', 2005a and 2005b]<br />
;Corbett: Ship emissions inventory as described in ''Corbett et al'' [1999].<br />
;EDGAR: SO2 ship emissions from the EDGAR 3.2 FT2000 global inventory.<br />
;EMEP: Ship emissions from the EMEP (European Monitoring and Evaluation Programme).<br />
;ICOADS: Emission inventory based on data from the nternational Comprehensive Ocean−Atmosphere Data Set (ICOADS), the Automated Mutual-Assistance Vessel Rescue System (AMVER) data sets [''Wang et al'', 2008].<br />
<br />
Starting with [[GEOS-Chem v8-01-04]], ship-emitted NOx is no longer emitted directly as NOx, but as the combination HNO3 + 10*O3, following ''Chen et al'' [2005].<br />
<br />
== ARCTAS ==<br />
<br />
The ARCTAS pre-mission inventory of SO2 was first introduced in [[GEOS-Chem v8-01-04]]. <br />
<br />
The source code is contained in file <tt>arctas_ship_emiss_mod.f</tt>.<br />
<br />
For more information about the data, please see the README file: [ftp://ftp.as.harvard.edu/pub/geos-chem/data/GEOS_1x1/ARCTAS_SHIP_2008/README GEOS_1x1/ARCTAS_SHIP_2008/README]<br />
<br />
'''''Philippe Le Sager wrote:'''''<br />
<br />
<blockquote>The ship emission is based on the work by ''Eyring et al.'', [2005a and 2005b], which estimates the total international ship emissions for 1985, 1990, 2001, and 2020 (projection). The ship emission for each individual year is interpreted based on the above years, and the spatial pattern (gridded) is mapped based on the EDGAR gridded ship emission for 2000 (total amount from EDGAR is scaled to Eyring-based number).</blockquote><br />
<br />
<blockquote>If you want to reference the work on publication or website, you may either mention ''Diehl et al.'' [manuscript in preparation, 2009] or refer to the [http://www-lscedods.cea.fr/aerocom/AEROCOM_HC/readme_ship AeroCom readme document] (prepared by Diehl).</blockquote><br />
<br />
== Corbett ==<br />
<br />
For more information about this inventory please see: Corbett, J. J., P. S. Fischbeck, and S. N. Pandis, ''Global nitrogen and sulfur inventories for oceangoing ships'', <u>J. Geophys. Res.</u>, '''104'''(D3), 3457–3470, 1999.<br />
<br />
The Corbett et al data are read from disk by routine <tt>READ_SHIP_SO2</tt> in <tt>sulfate_mod.f</tt>.<br />
<br />
For more information about the data files, please see the following README files:<br />

<br />
== EDGAR ==<br />
<br />
For more information about the data files, please see the following README document: [ftp://ftp.as.harvard.edu/pub/geos-chem/data/GEOS_1x1/EDGAR_200607/README GEOS_1x1/EDGAR_200607/README]<br />
<br />
The source code routines that read the EDGAR ship emissions data from disk are:<br />
<br />
#<tt>SEASCL_EDGAR_SHIP_SO2 (edgar_mod.f)<br />
#GET_EDGAR_SHIP_SO2 (edgar_mod.f)</tt><br />
<br />
The EDGAR ship SO2 emissions are reported as per year. Routine <tt>SEASCL_EDGAR_SHIP_SO2</tt> applies monthly scale factors (which are computed as the ratio of monthly/total ship SO2 emissions from the [[#Corbett|Corbett et al inventory]] to the annual EDGAR ship SO2 emissions. This is required to impose aseasonality onto the EDGAR ship SO2 emissions.<br />
<br />
== EMEP ==<br />
<br />
The EMEP inventory contains ship emissions for NOx, CO, SO2. <br />
<br />
The source code is located in file <tt>emep_mod.f</tt>. <br />
<br />
=== 1980 to 1989 ===<br />
<br />
EMEP ship data from 1980-1989 emit NOx as pure NOx (and not HNO3 + 10*O3). It was not possible to separate the NOx into HNO3 and O3 from this data set.<br />
<br />
See ''Auvray and Bey'' [2005] and [http://www.emep.int/publ/reports/2002/mscw_note_1_2002.pdf ''Vestreng and Klein'' <nowiki>[2002]</nowiki>] for more information.<br />
<br />
=== 1990 to 2005 ===<br />
<br />
EMEP ship data from 1990-2005 are based on [''Vestreng et al'', 2007].<br />
<br />
For more information about the data, please see the README file: [ftp://ftp.as.harvard.edu/pub/geos-chem/data/GEOS_1x1/EMEP_200911/README GEOS_1x1/EMEP_200911/README]<br />

<br />
== ICOADS ==<br />
<br />
The ICOADS ship inventory was first introduced in [[GEOS-Chem v8-02-03]]. It contains the species NOx, CO, and SO2. [mailto:cklee79@gmail.com Chulkyu Lee] worked on implementing ICOADS into GEOS-Chem. <br />
<br />
The source code is in file <tt>icoads_ship_mod.f</tt>.<br />
<br />
For more information about the data, see the README file: [ftp://ftp.as.harvard.edu/pub/geos-chem/data/GEOS_1x1/ICOADS_200907/README GEOS_1x1/ICOADS_200907/README]<br />
<br />
From [http://pubs.acs.org/doi/abs/10.1021/es0700799''Wang et al'' <nowiki>[2008]</nowiki>]:<br />
<br />
<blockquote>Ship activity patterns depicted by the International Comprehensive Ocean−Atmosphere Data Set (ICOADS), the Automated Mutual-Assistance Vessel Rescue System (AMVER) data set, and their combination demonstrate different spatial and statistical sampling biases. These differences could significantly affect the accuracy of ship emissions inventories and atmospheric modeling. We demonstrate (using ICOADS) a method to improve global-proxy representativeness by trimming over-reporting vessels that mitigates sampling bias, augment the sample data set, and account for ship heterogeneity. Apparent under-reporting to ICOADS and AMVER by ships near coastlines, perhaps engaged in coastwise (short sea) shipping especially in Europe, indicates that bottom-up regional inventories may be more representative locally. Primarily due to the long time series available publicly for ICOADS data, the improved ICOADS data set may be the most appropriate global ship traffic proxy identified to date to be used for a top-down approach. More generally, these three spatial proxies can be used together to perform uncertainty analyses of ship air-emissions impacts on a global scale (http://coast.cms.udel.edu/GlobalShipEmissions/).</blockquote><br />

=== Bug for ship emissions in emfossil.f ===<br />
<br />
'''''[mailto:g.c.m.vinken@tue.nl Geert Vinken] wrote:'''''<br />
<br />
:'''Problem:''' The ship NOx emissions are as HNO3 and O3. These are stored in the EMISRR array when the other NOx emissions are determined. However, when later on the HNO3 and O3 emissions are determined these entries in the EMISRR arrays are overwritten. This way the ship HNO3 and O3 emissions are lost and consequently no ship emissions are present in the model!<br />
<br />
:'''Code problem:''' In <tt>emissdr.f</tt> (line258) the fossil fuel emissions are called for all the emitted species.<br />

<br />
:Here the present HNO3 and O3 emissions from the NOx emissions are thus overwritten.<br />
<br />
:'''Fix:''' I think the following should fix this, as the EMISRR array is zeroed in every call to <tt>emissdr.f</tt> this should give no problems:<br />
<br />
!--------------------------------------------------------------<br />
! Store in EMISRR array and archive diagnostics<br />
!--------------------------------------------------------------<br />
!--- Prior to (gvinken, 11/16/10). Emissions already present in EMISRR<br />
! no longer get overwritten.<br />
! EMISRR(I,J,N) = EMX(1) * XNUMOL(NN) / DTSRCE<br />
EMISRR(I,J,N) = EMISRR(I,J,N) + EMX(1) * XNUMOL(NN) / DTSRCE<br />
<br />
This fix will be incorporated into an upcoming GEOS-Chem version. We will also issue a patch shortly.<br />

=== Inconsistent mask file for EMEP ship emissions ===<br />
<br />
'''''[mailto:g.c.m.vinken@tue.nl Geert Vinken] wrote:'''''<br />
<br />
:When I was looking at the ship emissions I noticed that the current mask that determines where to apply EMEP emissions, does not correspond anymore with the actual EMEP emissions. The mask still corresponds with the 200510 emissions data. This mismatch in the mask and the actual emissions results in no ship emissions being released over a region of the North Atlantic and north of Norway. <br />
<br />
:As a solution I updated the mask file to correspond with the new border of the EMEP emissions domain. I cut of the mask west of 30W and north of 70N. This fixes the problem.<br />

[[GEOS-Chem v9-01-01]] will use Geert Vinken's updated mask for EMEP ship emissions.<br />
