This experiment was performed in Australia in 1991 using the Commonwealth and Scientific Industrial Research Organisation's (CSIRO) 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 Gates et al. (1992) and McGregor et al. (1993) and is referred to as "CSIRO1" (this distinguishes it from a later model version, CSIRO2). Results from this experiment were obtained in 1994 from Peter Whetton at the 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 4.8deg C and the global precipitation sensitivity was 2.1% per deg Celsius warming.
Mean monthly precipitation pattern correlation coefficient = 0.64
