The Quasi-Geostrophic Coupled Model (Q-GCM) has been developed jointly by National Oceanography Centre (UK), Florida State University (USA) and The Australian National University (Australia).
Q-GCM is a mid-latitude, basin scale coupled ocean-atmosphere model. The basic model consists of a quasi-geostrophic channel atmosphere coupled to a simple, rectangular quasi-geostrophic ocean. Heat and momentum exchanges between the ocean and the atmosphere are mediated via embedded mixed layer models, and the system is driven by latitudinal variations in incident solar radiation.
Q-GCM is available for download under the GNU public license. The latest release, version 1.4.0, was released on July 4 2010 - go to the download page for more information. The new version includes the "relative velocity" wind stress scheme outlined by Duhaut and Straub (2006).
The model is currently being developed to include arbitary coastlines into the model. Expected release date of version 2.0.0 is early 2011.
