Model outputs generated by the Theory and Analysis Working Group are now available as netCDF files for individual stations from 1985-2017. They can be downloaded via anonymous ftp at the website ftp://ftp.cpc.ncep.noaa.gov/ndacc/gmi_model_data. The files are generated from a GMI chemistry transport model (CTM) simulation integrated with MERRA2 reanalysis meteorology. They have realistic constituent variability from daily to seasonal timescales.
