1-month full-chemistry benchmarks
1-month benchmark setup
The following table describes the GEOS-Chem setup for both GEOS-Chem Classic and GCHP 1-month benchmark simulations.
| Git tag(s): |
|
| Compared to previous benchmark: | 13.4.0 |
| 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: | TBD |
| Chemistry setup: | TBD |
| This version will impact: (select all that apply with boldface) |
|
1-month internal benchmarks
Each update that will introduce a significant change in the full-chemistry simulation is tagged with an alpha version in Git. For each of these alpha versions, the GCST runs an internal 1-month benchmark simulation to isolate the impact from that update.
For more details on the update(s) included in each alpha version and a link to benchmark results, see this Google sheet.
