| + | |
− | | + | |
− | === 1-month and 1-year benchmarks ===
| + | |
− | | + | |
− | For complete information about the benchmark simulations used to validate GEOS-Chem v11-03, please see [[GEOS-Chem v11-03 benchmark history|our ''GEOS-Chem v11-03 benchmark history'' wiki page]].
| + | |
− | | + | |
− | === Unit tests for GEOS-Chem v11-03 ===
| + | |
− | | + | |
− | 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 v11-03. Click on the links below to see the results from each set of unit tests:
