New data directories
The following HEMCO data directories have been added or updated for GEOS-Chem v11-02. You will have to download the directories relevant to your simulation.
Inventory | What was added? | When added? | Directory |
---|---|---|---|
TBD | TBD | TBD | TBD |
Validation
In this section we provide information about the benchmarks and tests that we have done to validate GEOS-Chem v11-01.
1-month and 1-year benchmarks
For complete information about the benchmark simulations used to validate GEOS-Chem v11-02, please see our GEOS-Chem v11-02 benchmark history wiki page.
Unit tests for GEOS-Chem v11-02
We perform a full set of unit tests on GEOS-Chem on an almost daily basis. These tests ensure that each new feature being added does not break any existing functionality.
Here are the unit tests that we ran before submitting 1-month benchmark simulation for v11-02. Click on the links below to see the results from each set of unit tests:
