README -- Describes contents of HEMCO/OFFLINE_DUST/v2019-01 directory 8 Apr 2019 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Overview: ============================================================================== Grid-independent offline dust emissions are now available for GEOS-Chem at native MERRA-2 (0.5° x 0.625°) and GEOS-FP (0.25° x 0.3125°) meteorology field\ resolution. Instructions to calculate the offline emissions can be found on the GEOS-Chem wiki: http://wiki.seas.harvard.edu/geos-chem/index.php/Mineral_dust_aerosols#Offline_Dust_Emissions.
