Checklist for preparing data files

1. If you have a data file that is in binary punch (bpch) file format, then create a netCDF file from the bpch file.
2. Once you have a netCDF file, determine which elements of the file are not compliant with the COARDS conventions
3. Edit non-conforming variable names, variable attributes, and/or global attributes to make them COARDS-compliant.
4. Regrid the data (if necessary).
5. Crop the data (e.g. if you are using a nested-grid simulation).
6. Chunk and deflate the file to reduce file size and improve I/O performance.

Submitting your files for inclusion to the GEOS-Chem data repository

If you would like to submit your data files for inclusion into standard GEOS-Chem data repository, then please follow our Guidelines for submitting code and data updates for GEOS-Chem.
