README 11 Mar 2019 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Olson_2001_Land_Type_Masks.025x025.generic.nc contains Olson 2001 land type data as binary masks (one mask variable per land type). The script to generate the file is ./scripts/make_OLSONXX_land_masks.ncl. This work was done so that the Olson land map could be read in and regridded by HEMCO. ~ Lizzie Lundgren, 4 Jan 2018 - Bob Yantosca, 11 Mary 2019
