GCAP 2.0

GEOS-Chem / GISS ModelE2.1 interface

GCAP 2.0 is set for inclusion into the GEOS-Chem standard code in version 13.1. Until then, one may obtain the beta release code in version 13.0.0 using the following commands.

git clone -b feature/GCAP2 https://github.com/ltmurray/GCClassic.git ./Code.GCAP2
cd Code.GCAP2
git submodule update --init --recursive
cd src/GEOS-Chem
git checkout feat/GCAP2
cd ../HEMCO
git checkout feat/GCAP2

Note that submodules always download in a headless state, requiring one to manually select a branch as above.

You may then follow the general directions for creating run directories and obtaining input files.

The GCAP 2.0 meteorology and emission files are located at http://atmos.earth.rochester.edu/input/gc/ExtData/, to which you can set remote_root in the download_data.py python script.

Please contact Dr. Murray with any questions or to report any issues.
