GEOS-Chem Classic 1-month benchmark
1-month benchmark plots
These benchmarks were primarily made with GCPy. Some benchmark plots created by GAMAP still remain because they have not been recreated in GCPy yet.

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.

GEOS-Chem Classic 1-year benchmark
1-year benchmark overview
In this 1-year benchmark, two GEOS-Chem model versions are compared to each other:
1-year benchmark plots
These benchmarks plots were made using a combination of routines from GCPy and GAMAP. The 6-panel concentration, difference, and fractional difference plots were created with GCPy, while the model vs observation plots, the emissions plots and tables, and the aerosol tables were created with GAMAP because they have not been converted to Python yet.
