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:
  • GFED4_climatology_2010-2023_05x0625.nc
  • GFED4_monmean_05x0625_2010-2023.nc
 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/
