NOTES:

  • Enable PDF bookmarks in the files linked above to navigate between species. See the Species in GEOS-Chem wiki page for species definitions and details. If you do not see bookmarks in your browser try using a different browser (not Safari) or installing an Adobe Acrobat plug-in.
  • Species categories and lumped species definitions are simple to adjust. Updating them requires only editing the YAML files.
