CoG is a collaboration environment that provides the Earth science community with a distributed data and computation platform that also supports project hosting and virtual collaboration networks. CoG is free and open source and can be downloaded and installed by anyone.
A cog is a wheel or gear in a multi-component mechanism. The term CoG is used to reflect the many functional pieces/tools that make projects in the Earth sciences successful.
In 2016, CoG became the Web Front End to the Earth System Grid Federation. As such ESGF nodes also have CoG projects and use the CoG search to access data. CoG can be installed without ESGF.
You only need to sign up for an account if you want to join a project or you need to download data.
We maintain a list of tutorials covering all aspects of CoG functionality.
Questions related to data should be sent to firstname.lastname@example.org. They are based in Germany.
