Overview:
===============================================================================

These files are chemical production and loss rates that are needed for the
GEOS-Chem CO2 simulation.  They appear to have been archived from GEOS-Chem
simulations.

The original data were stored in binary punch (bpch) files in the older
GEOS-Chem data directory: GEOS_2x2.5/CO2_201003/ChemSrc.

Christoph Keller converted these files to COARDS-compliant netCDF for
compatibility with HEMCO.
