README -- Describes contents of HEMCO/XIAO/v2014-09 directory 11 Feb 2015 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Overview: =============================================================================== Yaping Xiao's C2H6 and C3H8 emission data (Xiao et al., JGR, 2008). We currently use Xiao C2H6 emissions to overwrite the RETRO C2H6 emissions (cf: http://wiki.seas.harvard.edu/geos-chem/index.php/Implementation_of_RETRO_Anthropogenic_Emissions#RETRO_anthropogenic_ethane_emissions_are_too_low). Original bpch-files from /data/geos/GEOS_XX/C3H8_C2H6_200109, where XX is the resolution (4x5 or 2x25). Regridding onto the 1x1 grid was done using 'cdo remapbil,geos.1x1.grid C3H8_C2H6_ngas.geos.2x25.nc C3H8_C2H6_ngas.geos.1x1.nc' -- Christoph Keller, 09/29/12 Files: =============================================================================== C3H8_C2H6_ngas.geos.1x1.nc -- Xiao et al C2H6 and C3H8 emissions.
