GEOS-Chem Main Page | GCHP Main Page

On this page we list the current priorities for GEOS-Chem development. This list is continuously updated based on code readiness and input from the Working Groups and the Steering Committee.

GEOS-Chem versions in development

13.1.0

See the GEOS-Chem 13.1.0 page for more details.

Priorities assigned to upcoming GEOS-Chem versions

13.2.0

See also the 13.2.0 milestone on Github.

This version will require a 1-month full-chemistry benchmark and 1-year full-chemistry and transport tracer benchmarks, with and without Luo wet deposition.
