In IPSL-CM3, the atmospheric model is LMDZ3.2 (Li, 1999). The standard resolution for this model is 4°x5° for the atmosphere (72x45xL19), 1.5°x2° (with a meridional resolution of 0.5° near the Equator, L31) for the ocean. With this model, a first long term 1000-year simulation has been performed (Li and Conil, 2003).
