Fit parameters and GEOS-Chem output for emulator of effects of meteorology on ozone, NOx, and PM2.5

Emulator of effects of meteorology on surface ozone, NOx, and PM2.5 over eastern Canada. Based on output of GEOS-Chem simulations (version 13.3.4, doi:10.5281/zenodo.5764874) over eastern Canada (35 N to 65 N, 90 W to 50 W) at 0.5x0.625 degree resolution. Simulations spanned 1981-1985, 1990-1994, 2000-2004, and 2010-2014 inclusive.

Fit parameters were derived by singular value decomposition followed by multi-linear regression. See accompanying papers for details.

Each file contains the spatially-gridded fit parameters for a single sensitivity simulation (base, noQC, noCA, or noUS), month of year, and output species (O3, NOx, PM2.5, or component species of PM2.5: black carbon (BC), mineral dust smaller than 2.5 microns (DSTPM2.5), ammonium (NH4), nitrate (NIT), fine sea-spray (SALA), organic aerosol (OA), and sulphate (SO4) ). Temporal means and temporal variability of the meteorological data are also included in files with fit parameters for convenience.

Output from GEOS-Chem has been subset to the lowest model level to keep the size of the archive within required limits. Further, while output is daily resolution, each year from each simulation has been archived together using tar.
