New data directories
The following data directories have been added or updated in this version. You will have to download the directories relevant to your simulation.
Inventory | Simulations | What was added? | Directory |
---|---|---|---|
GEOS-FP | All | Native GEOS-FP met fields at c720 resolution (~12 km), includes mass fluxes and derived winds. Using these fields is an option in GCHP. | ExtData/GEOS_C720 |

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.
