This directory contains sample netCDF restart files that can be used to initialize
GEOS-Chem simulations.

The GEOS-Chem Classic "fullchem" restart files here were obtained from the
10-year benchmark simulation for GEOS-Chem 14.0.0-rc.3 using MERRA-2 4x5
meteorology. Restart files for the entire 2010-2019 period may be found at
http://ftp.as.harvard.edu/gcgrid/geos-chem/10yr_benchmarks/14.0.0/GCClassic/Restarts/.

The GEOS-Chem Classic "TransportTracers" restart files were obtained from the
1-year Transport Tracer benchmark simulation for GEOS-Chem 14.0.0-rc.3 using
MERRA-2 4x5 meteorology.

All GCHP restart files were regridded from the GEOS-Chem Classic restart files
using scripts/convert_GCC_rst_to_GCHP_rst.sh with fortran regridding tool
csregridtool (https://bitbucket.org/sdeastham/csregridtool/).

%%% IMPORTANT: It is highly recommended that you do not use these restart   %%%
%%% files for any of your production runs. Rather, you should generate your %%%
%%% own restart file by spinning up the model for at least one year to      %%%
%%% produce a new restart file.                                             %%%
