Version history summary
| Past releases | Future releases |
The sections below describe each GEOS-Chem feature version and GEOS-Chem bug fix patch version belonging to the GEOS-Chem 12 series. Each feature version carries the tag 12.Y.0, which indicates that the version will be (or has been) validated with a 1-month benchmark simulation (and one or more 1-year benchmark simulations if necessary). Each patch version carries the tag 12.Y.Z, which denotes that the version preserves backwards-compatibility with the prior feature version 12.Y.0. For more information, please see our GEOS-Chem version numbering system wiki page.
Several GEOS-Chem updates have been proposed by the relevant Working Groups, but have not yet been assigned to a specific GEOS-Chem version. For a complete list of these updates, please visit our GEOS-Chem model development priorities wiki page.
Previously released stable versions
We list below past releases of GEOS-Chem. But we recommend that you always download the current stable version listed above when starting a new research project. That version corresponds to the main branch of the GEOS-Chem source code repository on Github.
Each released version of GEOS-Chem will be assigned a unique Digital Object Identifier (DOI). This will allow you to cite each GEOS-Chem version in publications. We also have obtained a "Concept DOI", which will always point to the current stable version of GEOS-Chem: DOI 10.5281/zenodo.1343546. This can be convenient if you wish to cite GEOS-Chem without making reference to a particular version.

New data directories in 12.1.0
The following data directories have been added or updated in this version. You will have to download the directories relevant to your simulation.
| Inventory | Type | What was added? | Directory |
|---|---|---|---|
| DUST DEAD | DEFAULT | Anthropogenic PM2.5 dust source | HEMCO/DUST_DEAD/v2018-04/ |
| GEOS-Chem restart files | DEFAULT | GEOS-Chem restart file updates: New variables, new variable names, new file names | GEOSCHEM_RESTARTS/v2018-11/ |
| Input files for FAST-JX | DEFAULT | Move Fast-JX .dat files from the geos-chem-unittest repository to gcgrid/ExtData | CHEM_INPUTS/FAST_JX/v2018-09/ |
| RRTMG input data | OPTIONAL | netCDF input data files for the RRTMG specialty simulation (converted from the old "binary punch" format files) | HEMCO/RRTMG/v2018-11/ |
| CEDS anthropogenic emissions | DEFAULT | Reduce file size for CEDS inventory | HEMCO/CEDS/v2018-08/YYYY |
