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

Performance statistics: |
|
Compared to previous benchmark: | v9-02a |
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/pub/exchange/mpayer/1mo_quick_look/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: | At first sight, the changes look as expected. Some of the 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: | |
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: | |
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. |
