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
GFED4 biomass burning Several
  • Dry matter data and scale factors for additional years 2020 - Oct 2022
  • Climatology emissions for 2010-2019 and monthly mean emissions for 2007-2021 (current GFED4 record) generated by a 0.5x0.625 HEMCO standalone simulation
