|
Version, resolution, met fields used: | v9-02, GEOS-5 (47L), 4x5 |

This update will impact: (select all that apply with boldface) |
Advection, BL Mixing, Convection, Met Fields, Dry Dep, Wet Dep, Stratosphere, Anthro Emiss, Biogenic Emiss, Biomass Emiss, Photolysis, Chemistry, Other (please specify): We expected to see no changes from v9-02d. We have only made structural modifications but not scientific modifications. |
Plots may be viewed at: | ftp://ftp.as.harvard.edu/gcgrid/geos-chem/1mo_benchmarks/v9-02/v9-02d/ |
Metrics | |
Global mean OH (from log file): | 12.9397354478399 x 105 molec/cm3 |
Methyl chloroform lifetime: | 4.8586 years |
Did either of these change by more than 5%? | No |
At the SURFACE, list all species that changed by 10% or more: | NIT |
Comments on SURFACE differences: | Differences in NIT are attributed to the numerical noise issue in ISORROPIA II. |
At 500 hPa, list all species that changed by 10% or more: | ISOP, NH3, NIT |
Comments on 500 hPa differences: | Differences are seen in ISOP in locations where concentrations are already very low (i.e. over oceans). These differences are attributed to the bromine bug fix.
Differences in NH3 and NIT are attributed to the numerical noise issue in ISORROPIA II. |
In the ZONAL MEAN differences, list all species that changed by 10% or more: | ALK4, ISOP, PRPE, C3H8, SO4s, NH3, NIT, NITs, Br2, |
Comments on ZONAL MEAN differences: | Differences are seen in ALK4, ISOP, PRPE, C3H8, SO4s, and Br2 are in locations where concentrations are already very low. These differences are attributed to the bromine bug fix.
Differences in NH3 and NIT are attributed to the numerical noise issue in ISORROPIA II. |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | None |
Comments on EMISSION RATIO differences: | |
Additional or summary comments: | When ISORROPIA is turned off, and when the Bug fix for Br2 emissions is also added to v9-02c, then we obtain identical results between v9-02c and v9-02d. This demonstrates that the structural modifications made for grid independence do not change GEOS-Chem's scientific results. Most of these modifications were made to carry data fields in derived-type objects rather than in module arrays, but the data fields themselves have not changed. |

Developer name(s) and institution(s): |
|
Version, resolution, met fields used: | v9-02, GEOS-5 (47L), 4x5 |

This update will impact: (select all that apply with boldface) |
Advection, BL Mixing, Convection, Met Fields, Dry Dep, Wet Dep, Stratosphere, Anthro Emiss, Biogenic Emiss, Biomass Emiss, Photolysis, Chemistry, Other (please specify): Soil NOx emissions |
Plots may be viewed at: | ftp://ftp.as.harvard.edu/gcgrid/geos-chem/1mo_benchmarks/v9-02/v9-02b/ |
Metrics | |
Global mean OH (from log file): | 12.9398281506753 x 105 molec/cm3 |
Methyl chloroform lifetime: | 4.8585 years |
Did either of these change by more than 5%? | No |
At the SURFACE, list all species that changed by 10% or more: | NOx, Ox, PAN, ALK4, ISOP, HNO3, H2O2, MEk, ALD2, RCHO, MVK, MACR, PMN, PPN, R4N2, PRPE, C3H8, CH2O, N2O5, HNO4, MP, DMS, SO2, SO4, SO4s, MSA, NH3, NH4, NIT, NITs, Br2, Br, BrO, HOBr, HBr, BrNO2, BrNO3, and OH |
Comments on SURFACE differences: | The changes are as expected. The new soil NOx parameterization significantly increases the NOx concentrations over North America, the southern part of South America, Central Asia and parts of Africa. Decreases occur over the northern part of South America, central Africa and Indonesia.
Other species are influenced by resulting changes in O3 (and consequently OH). However, some of the reported changes are mainly caused by noise since the absolute differences are very close to zero. |
At 500 hPa, list all species that changed by 10% or more: | NOx, PAN, ALK4, ISOP, HNO3, MEK, ALD2, RCHO, MVK, MACR, PMN, PPN, PRPE, N2O5, HNO4, MP, DMS, SO2, MSA, NH3, NIT, NITs, Br2, Br, BrO, HOBr, HBr, BrNO2, BrNO3, and OH |
Comments on 500 hPa differences: | See 'Comments on SURFACE differences' |
In the ZONAL MEAN differences, list all species that changed by 10% or more: | NOx, PAN, ISOP, HNO3, MEK, RCHO, MVK, MACR, PMN, PPN, PRPE, N2O5, HNO4, DMS, SO4s, NH3, NIT, NITs, Br, BrO, BrNO2, BrNO3 and OH. |
Comments on ZONAL MEAN differences: | See 'Comments on SURFACE differences' |
In the EMISSION RATIO maps, list all species that changed by 10% or more: | NOx fertilizer emissions and NOx soil emissions |
Comments on EMISSION RATIO differences: | The NOx soil emissions diagnostic now includes the NOx fertilizer emissions since the emissions related to fertilizer are now calculated using the same procedure as the “regular” soil emissions based on the biome emission coefficients. The soil NOx emission total increases with 0.310 Tg N to 1.028 Tg N for July.
The fertilizer emissions diagnostics gives the soil NOx emissions related to fertilizer use and deposited nitrogen. |
Additional or summary comments: | The occurring changes are as expected. The benchmark is performed using a new soil NOx restart file which saves per grid cell:
The overall changes are in NOx emissions are consistent with those in Hudman et al. (2012) with the additional canopy reduction that Bram added. The changes in O3 and OH follow the changes in NOx emissions. |
