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 |
|---|---|---|---|
| Aerosol optics | aerosol-only fullchem |
Configuration files (brc.dat, dust.dat, h2so4.dat, org.dat, so4.dat, soot.dat, ssa.dat, ssc.dat containing optical properties were copied here. Used for computing AOD. | ExtData/CHEM_INPUTS/Aerosol_Optics/2024-08/ |
| GFED4 climatology | fullchem | Climatology and monthly-mean emissions for period 2010-2023, with species that were added in 14.5.0, namely:
|
ExtData/HEMCO/GFED4/v2023-03/ |
| Cloud-J inputs | fullchem | Copy of v2023-05 with H2O UV absorption cross-sections added, species PPN added, and aerosol dat-files used for computing AOD in GEOS-Chem removed. | ExtData/CHEM_INPUTS/CLOUD_J/2024-09/ |
| Cloud-J inputs | Hg | Copy of v2023-11-Hg with H2O UV absorption cross-sections added and aerosol dat-files used for computing AOD in GEOS-Chem removed. NOTE: Cloud-J in Hg simulation is in development. |
