This experiment was performed in Germany in 1995 using the Max Planck Institute's T21 19-layer atmospheric GCM, coupled to an 11-layer LSG ocean model. The horizontal resolution of the atmospheric model is 5.6 deg. latitude by 5.6 deg. longitude and the ocean model is 2.8 deg. latitude by 2.8 deg. longitude. ECHAM3-TR is a transient experiment in which the year-by-year greenhouse gas forcing is supplied by the IPCC 1990 Scenario BaU A emissions scenario. It is a "warm-start" experiment, in that historic forcing was introduced to the model prior to the Scenario A forcing scenario commencing in 1990. The experiment is reported in Kattenburg et al. (1996) and is widely referred to as "MPI" (this is too vague a description, hence our terminology). We acquired the results from this experiment in 1996 via ftp from the Max Planck Institute in Hamburg. The greenhouse gas only change fields used in SCENGEN are calculated as the difference in climate between the 30-year means of years 2055-2084 and 1961-1990 in the greenhouse gas only forced simulation. The global warming by this decade, with respect to 1961-1990, was 3.2deg C and the increase in global precipitation was ?%. The climate sensitivity of the same atmospheric model, coupled to a mixed-layer ocean, was 2.6deg C.
Mean monthly precipitation pattern correlation coefficient = 0.67
