1-month internal benchmarks
Each update that will introduce a significant change in the full-chemistry simulation is tagged with an alpha version in Git. For each of these alpha versions, the GCST runs an internal 1-month benchmark simulation to isolate the impact from that update.
For more details on the update(s) included in each alpha version and a link to benchmark results, see this Google sheet.

The monthly mean output includes several diagnostics, including AerosolMass, Aerosols, JValues, ProsLoss, and SpeciesConc among many others. These output are used as input in the aerosol-only, CH4, POPs, tagCH4, tagCO, tagO3 starting in GEOS-Chem 14.0.2.
The restart files may be used to initialize full-chemistry GEOS-Chem simulations. For more information see the Restart files chapter of geos-chem.readthedocs.io.
