README -- Contents of HEMCO/BIOFUEL/v2019-08 directory 07 Aug 2019 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Overview: =============================================================================== This directory contains annual biofuel emissions files from the Yevich & Logan (2003) inventory. The data is the same as in HEMCO/BIOFUEL/v2014-07 but has been conservatively regridded from 4x5 to 2x2.5. This is to address the following issue in v2014-07 files at higher resolution than 4x5: "Christoph Keller created netCDF files from the original binary punch files in the prior biofuel_200202/ directory folder. ==> It turns out that biofuel SO2 emissions in some regions are very different (up to a factor of 2 for some grid boxes) when using the high-resolution biofuel field compared to the 4x5 degrees input file. For backwards consistency, we recommend using the 4x5 biofuel file instead of the 1x1 file." For more information about this inventory, please see this wiki page: http://wiki.geos-chem.org/Biofuel_emissions#Yevich_.26_Logan_inventory See also the README in HEMCO/BIOFUEL/v2014-07 for information about the source 4x5 file from which this file was regridded.
