This page includes information about all benchmark simulations for GEOS-Chem 12.5.0.
GEOS-Chem Classic 1-month benchmark

NOTES:
- At present, we have only created the diff-of-diffs plots for species concentration. This can be extended to other categories in the future.
Special benchmarks
In this section we list information about special (i.e. non-official) benchmark simulations that were performed. These are often necessary to validate certain model features.
GEOS-Chem Classic 12.5.0 BPCH vs. netCDF
A GEOS-Chem "Classic" 12.5.0 simulation was performed in order to compare the differences between using binary punch (aka BPCH) diagnostic output and netCDF diagnostic output. This is a necessary step before we can remove the BPCH diagnostics completely from GEOS-Chem.
