The CFMIP2 GCM experiments are now being coordinated as part of the CMIP5 project.
The CFMIP experiments are described in Section IV of the CFMIP-2 experimental design and appear in Table 6 of the CMIP5 experimental design.
An overview of the CFMIP model output requirements appears in Section III of the CFMIP-2 experimental design and details are available in the CMIP5 List of Required Model Output (Please note that the latter document is not finalised, and that some additional output requests will appear when the definitive version is published.)
A patterned SST forcing dataset is required for experiment 6.6. This is a normalised multi-model ensemble mean of the ocean surface temperature response pattern (the change in ocean surface temperature (TOS) between years 0-20 and 140-160, the time of CO2 quadrupling in the 1% runs) from thirteen CMIP3 AOGCMs (cccma, cnrm, gfdlcm20, gfdlcm21, gisser, inmcm3, ipsl, miroc-medres, miub, mpi, mri, ncar-ccsm3, and ncar-pcm1.) Before computing the multi-model ensemble mean, each model's TOS response
was divided by its global mean and multiplied by 4. This
guarantees that the pattern information from all models is weighted
equally and the global mean SST forcing is the same as in the uniform +4K
experiment (6.8 in the CMIP5 expt. design document).

Please note that CFMIP SST perturbation experiments (6.5, 6.6, 6.8) do not perturb sea ice, which should be kept at control values, as for experiment 3.3. ( Updated 29th Oct, 2009)
For information on setting up the CFMIP aquaplanet experiments, please refer to Brian Medeiros's CFMIP-2 Aquaplanet information.
The list and plot of locations for high frequency CFMIP outputs is also now available. (Updated with three additional Arctic points to give a total of 118 - 2nd Sep 2009.) (Updated to include locations for aquaplanet experiments - Jan 2010.)
