The IPSL-CM6 will be the next version of the IPSL model and will be a full earth system model. In addition to the physical atmosphere-land-ocean-sea ice model based on the LMDz, ORCHIDEE, NEMO and LIM models, it also includes a representation of the carbon cycle. Modules for interactive stratospheric chemistry and tropospheric chemistry with aerosols can be activated. The IPSL climate model uses the OASIS coupler and the powerful XIOS input/output server.
Here is a wiki page that explains the work in progress: http://forge.ipsl.jussieu.fr/igcmg/wiki/IPSLCM6
A full description and references will be coming at a later stage.
