GEOS-Chem v11-01 benchmark history

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

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%.

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). 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).
