On this page we have posted complete information about all benchmark simulations (both 1-month and 1-year) for GEOS-Chem v11-01.

1-year benchmarks

1-month benchmarks

v11-01a

Here is the assessment form for 1-month benchmark simulation v11-01a.

  • NOTE: Unit tests for tagged CO were not performed, since this simulation is not yet 100% compatible with HEMCO.

Metrics
Global mean OH (from log file): 12.5726451325898 x 105 molec/cm3
Methyl chloroform lifetime: 4.9926 years
Did either of these change by more than 5%? No. The mean OH differs by 0.50%, and the MCF lifetime differs by -0.58%.
At the SURFACE, list all species that changed by 10% or more: NO, ISOP, HNO3, MVK, MACR, PMN, N2O5, NH4, NIT, NITs, OCPO, DST1, DST2, DST3, DST4, Br, BrO, HOBr, ISOPN, MOBA, GLYC, MMN, RIP, IEPOX, BrCl, Cl, ClO, ClNO2, ClOO, OClO, Cl2, Cl2O2, MTPA, LIMO, MTPO, ASOA2, ASOA3
Comments on SURFACE differences:
At 500 hPa, list all species that changed by 10% or more: NO, ISOP, HNO3, MVK, MACR, PMN, PRPE, NH3, NIT, OCPO, DST3, DST4, Br, ISOPN, MOBA, GLYC, RIP, IEPOX, BrCl, Cl, ClO, ClNO2, ClOO, OClO, Cl2, Cl2O2, MTPA, LIMO, MTPO
Comments on 500 hPa differences:
In the ZONAL MEAN differences, list all species that changed by 10% or more: NO, ALK4, ISOP, HNO3, MVK, MACR, PMN, PRPE, C3H8, N2O5, SO4s, NH3, NIT, NITs, BCPO, OCPO, DST1, DST2, DST3, DST4, SALC, Br, HBr, BrNO3, ISOPN, MOBA, HAC, GLYC, MMN, RIP, IEPOX, OCS, BrCl, CCl4, CH3CCl3, CFC11, H1211, H1301, H24O2, Cl, ClO, ClNO2, ClOO, OClO, Cl2, Cl2O2, MTPA, LIMO, MTPO, TSOA2, ISOA2, TOLU,
Comments on ZONAL MEAN differences:
In the EMISSION RATIO maps, list all species that changed by 10% or more: None
Comments on EMISSION RATIO differences:
  • The emission totals for NO changed slightly for several sources: soil and fertilizer (both by -0.000030 Tg N), anthropogenic + biomass burning (by 0.000081 Tg N), and lightning (by 0.005719 Tg N). Because NO emissions are dependent on the atmospheric concentration of NOx, we believe that the small changes are due to changes in the NOx atmospheric concentration associated with the air quantity moisture fixes.
  • The emission totals for hydrophilic tracer from hydrophobic tracer changed slightly for brown carbon (by -0.004145 Tg C) and organic carbon (by -0.012820 Tg C).
