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
OFFLINE_BIOVOC Full-chemistry;
Aerosols 		Updated offline biogenic VOC emissions to include the following updates based on GEOS-Chem 13.2.0:
  • Use new version Yuan-processed MODIS LAI (v2021-06);
  • Fix the unit bug for soil NOx emission;
  • Add methanol (MOH);
  • All emissions are now all in kg species/m2/s instead of kgC/m2/s

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.
