CSIRO2EQ

This experiment was performed in Australia in 1995 using the Commonwealth and Scientific Industrial Research Organisation's (CSIRO) Mark 2 R21 9-layer atmospheric GCM, coupled to a mixed-layer ocean. The horizontal resolution of the model is approximately 3.2 deg. latitude by 5.6 deg. longitude. It is an equilibrium experiment reported in Watterson et al. (1997) and is referred to here as "CSIRO2" (this distinguishes it from an earlier version of the CSIRO model - Mk 1 - used in SCENGEN and called "CSIRO1"). We acquired the results from this experiment in 1996 from Roger Jones in the Division of Atmospheric Research, CSIRO, in Melbourne, Australia. The change fields used in SCENGEN are calculated as the difference in climate between the 30-year means of the control (1xCO2) and perturbed (2xCO2) simulations. The climate sensitivity of the experiment was 4.3deg C and the global precipitation sensitivity was ?%.

Mean monthly precipitation pattern correlation coefficient = 0.71
