On this page, we describe how to download (aka "clone") the GEOS-Chem source code with Git.
Cloning the current GEOS-Chem version
The GEOS-Chem source code repository is available for remote download via Git, from our Github repository:
The first time that you will download a new GEOS-Chem version to your disk space, you must use the git clone command. This will create an exact copy of the GEOS-Chem source code (including the complete version control history) to a folder on your disk.
To clone the current version of GEOS-Chem, type:
git clone https://github.com/geoschem/geos-chem.git LOCAL_DIR_NAME
where LOCAL-DIR-NAME is the name of the local directory on your disk into which the GEOS-Chem source code files will be placed. It is up to you to pick LOCAL-DIR-NAME.
The GEOS-Chem source code that you downloaded will be a copy of the master branch, which always points to the current stable GEOS-Chem version. (More about Git branches in a couple of chapters.)
Cloning an older GEOS-Chem version
You can also clone an older GEOS-Chem version by using the -b option with git clone. This will copy the GEOS-Chem source code to your folder, and point the code to the branch or the tag that you specify. (For more information about Git branches and tags, then please see our Viewing the revision history page.
For example, to clone a copy of the GEOS-Chem 12.0.0 code, type:
git clone -b 12.0.0 https://github.com/geoschem/geos-chem.git LOCAL_DIR_NAME git checkout 12.0.0
This will download the GEOS-Chem source code and point you to the state of the code corresponding to the GEOS-Chem 12.0.0 release.
Cloning Git-backed software other than GEOS-Chem
You can clone any software package (not just GEOS-Chemn!) that has been saved to a Git repository. The only thing different that you have to specify is the path to the remote repository, and optionally, the name of the local folder into which the code will be copied.
