NOTES:
- Species category and lumped species definitions are simple to adjust. Updating them requires only editing the json files.
- All plots created with GCPy have PDF bookmarks. If you do not see them in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.

Comparison of bpch vs. netCDF diagnostic output in GEOS-Chem 12.5.0
In order to assess if there are any unaddressed issues with the implementation of the GEOS-Chem "History" diagnostics, we performed a comparison of the bpch diagnostic output ("Ref" version) vs. the netCDF diagnostic output ("Dev" version). These plots were generated from the diagnostic output of the 1-month benchmark for GEOS-Chem 12.5.0 (listed above).
