Revision as of 13:00, 26 October 2012

On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem v9-02.

1-year benchmarks

1-month benchmarks

v9-02b

Here is the assessment form for 1-month benchmark simulation v9-02b.

Description
New features added into GEOS-Chem:
Developer name(s) and institution(s):
  • Soil NOx: Rynda Hudman Kay (EPA); Neil Moore (formerly of Dalhousie); Bram Maasakkers (Eindhoven)
  • Bug fix in hdf_mod.F: Sajeev Philip (Dalhousie)
  • Tagged CO simulation fixes: Jenny Fisher (Wollongong); GEOS-Chem Support Team
  • Bug fix in nei_anthro_mod.F: Sajeev Philip (Dalhousie)
Version, resolution, met fields used: v9-02, GEOS-5 (47L), 4x5
1-month benchmark finished on: Wed Oct 24 16:10:25 EDT 2012
Performance statistics:
  • Ran on 8 CPUs of bench@titan-08.as.harvard.edu (2.659 GHz x 8 CPU)
  • Wall time: 2:19
  • Scalability: 6.5256
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.
Additional or summary comments:
