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 [[GEOS-Chem model development priorities|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 [https://github.com/geoschem/geos-chem 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: [https://doi.org/10.5281/zenodo.1343546 '''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 12.9.0 ====
  
The sections below describe each '''GEOS-Chem feature version''' and '''GEOS-Chem 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.
+
The following data directories have been added or updated in this version.  You will have to [[Downloading_GEOS-Chem_data_directories|download the directories]] relevant to your simulation.

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.

12.9.3

This version contains additional fixes for bugs and technical issues discovered after the release of 12.9.2.

This version was released on 06 Aug 2020.

DOI: 10.5281/zenodo.3959279

This version contains additional fixes for bugs and technical issues discovered during the 12.9.0 benchmarking process.

You can use the following Git commands to download the GEOS-Chem 12.9.2 source code and GEOS-Chem Unit Tester package.

NOTE: In GEOS-Chem 13.0.0 and later versions, run directory generation will be moved to the GEOS-Chem source code repository. The Unit Tester repository will be retired.
