README -- describes contents of HEMCO/POPs/v2015-08 directory 27 Feb 2017 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Overview: =============================================================================== This directory contains the relevant data files for the GEOS-Chem POPs simulations. All files have been ported to netCDF format for compatibility with the Harvard-NASA Emissions Component (HEMCO). Units have also been standardized.
