1-month benchmarks
1-month fullchem: Model setup
The following table describes the GEOS-Chem setup for both GEOS-Chem Classic and GCHP 1-month benchmark simulations.
Git tag(s): |
NOTE: 13.3.0-rc.0 was the original GC-Classic benchmark. During benchmarking of GCHP 13.3.0-rc.0, it was discovered that floating point numerical errors was causing GCHP benchmarks to fail. A fix was added, which was tagged with 13.3.0-rc.1. |
Compared to previous benchmark: | 13.2.0 |
Software environment: | gcc 10.2.0 OpenMPI 4.1.0 netcdf-fortran 4.5.3 CMake 3.17.3 ESMF 8.0.1 |
Model resolution: |
|
Meteorology fields: | MERRA-2
|
Initial conditions: | July 1, 2019
|
Benchmark month: | July 2019 |
Emissions setup: | HEMCO_Config.rc |
Chemistry mechanism: | fullchem.eqn |

NOTES:
- Enable PDF bookmarks in the file links to navigate between species. If you do not see bookmarks in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.
- See the species database for species definitions and details.
- Species categories and lumped species are defined in YAML files within the GEOS-Chem post-processing software GCPy.
