NOTES:
- 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.

Additional or summary comments: | The bug fixes for FAST-JX resulted in very small changes w/r/t the 12.3.0 1-month benchmark:
The fix to make species H2402 consistent between GCHP and GC "Classic" resulted in very minor additional changes on top of the FAST-JX fixes:
So it appears that most of the changes between 12.3.0 and 12.3.2 are being driven by the bug fixes to FAST-JX. | ||||||||||||||||||||||
