README -- Describes contents of HEMCO/OFFLINE_AEROSOL/v2014-09 27 Feb 2017 GEOS-Chem Support Team geos-chem-support@g.harvard.edu Overview: =============================================================================== These files are used by GEOS-Chem's "aerosols-only" specialty simulation. They were created from the corresponding binary punch files in the old directory "sulfate_sim_200508/offline". NOTE: Many of these files are of very old vintage and probably should be brought up to date by an interested party. Files: =============================================================================== ############################################################################### ##### NOTE: The netCDF file attribute 'lev:positive = "up"' was added ##### ##### to all files in OFFLINE_AEROSOL/v2014-09 having a vertical ##### ##### dimension. This was done to facilitate reading these files ##### ##### with GCHP. ##### ##### -- Bob Yantosca (27 Feb 2017) ##### ############################################################################### J(H2O2) ------------------------------------------------------------------------------- JH2O2.geos5.2x25.nc : File w/ J(H2O2) values ("JV-MAP-$", tracer 3) archived from a GEOS-5 1-yr simulation at 2 x 2.5 resolution.
