Here we have posted links to a separate wiki page describing each GEOS-Chem model version.
This page contains links to wiki pages describing past GEOS-Chem model releases. For information about upcoming releases see the [[GEOS-Chem model development priorities|'''GEOS-Chem model development priorities wiki page''']].

Latest revision as of 15:32, 20 November 2024

This page contains links to wiki pages describing past GEOS-Chem model releases. For information about upcoming releases see the GEOS-Chem model development priorities wiki page.

GEOS-Chem development history

In the tables below, we list information about current and past GEOS-Chem releases.

Some notes for the tables below:

  • Information about benchmarks can be found by following the links in the "Benchmarks" column
  • GCC = GEOS-Chem "Classic" (uses OpenMP parallelization single node only)
  • GCHP = GEOS-Chem High Performance (uses MPI parallelization across multiple nodes)
  • DOI = digital object identifier, can be used to reference individual GEOS-Chem versions in publications
  • AMI = Amazon Machine Image, which provides GEOS-Chem Classic on the AWS Cloud

Also see our GEOS-Chem version numbering system wiki page for information on how GEOS-Chem versions are labeled.
