README -- describes contents of MODIS_CHLR/v2019-11 directory 19 Nov 2019 GEOS-Chem Support Team geos-chem-support@g.harvard.edu These files were copied from the data files in: ExtData/CHEM_INPUTS/MODIS_LAI_201204/For_Olson_2001/ MODIS Chlorophyll-A files: =============================================================================== Data corresponding to actual years (2005-2014): ------------------------------------------------- MODIS.CHLRv.V5.generic.025x025.YYYY.nc -- Monthly MODIS-Aqua Chlorophyll-A data Provided by Matthew Johnson Email: matthew.s.Johnson@nasa.gov Resolution : 0.25 x 0.25 GENERIC grid (1440 x 720 grid boxes) Units : mg m-3 Compression : Level 1 (e.g. nccopy -d1) Timestamps: : Monthly, YYYY/01/01 through YYYY/12/01, where YYYY is the year listed in the file name For other dates, we provide climatological data: -------------------------------------------------- MODIS.CHLRv.V5.generic.025x025.Clim.nc -- Climatological MODIS Aqua Chl-a on the 0.25 x 0.25 GENERIC GRID. Provided by Matthew Johnson Email: matthew.s.Johnson@nasa.gov Resolution : 0.25 x 0.25 GENERIC grid (1440 x 720 grid boxes) Units : mg m-3 Compression : Level 1 (e.g. nccopy -d1) Timestamps: : Monthly, YYYY/01/01 through YYYY/12/01, where YYYY is the year listed in the file name NOTES about MODIS Chlorophyll-A files: -------------------------------------------------- (1) These files are at the same native resolution (0.25 x 0.25 GENERIC GRID) as the Olson 2001 landmap. The marine oraganic aerosol emission code is designed to regrid and apply CHLR files similar to the way LAI files are used. (2) NOTE: At present the CHLR data files are not read via HEMCO, but this may be done in a later update. Before this can be done, however, the units must first be changed to kg/m3 for compatibility with HEMCO. (bmy, 7/16/15)
