GISS MODEL II NINE LAYER CONTROL RUNS There are a number of different modern control runs for the paloeclimate experiments. It is important to be sure that the correct control run is used when evaluating the paleoclimate simulations. 822D is the standard Model II 8x10 mainframe control run with fixed sea surface temperatures 848 is the standard Model II 4x5 mainframe control run with fixed sea surface temperatures 882 is the standard Model II 8x10 mainframe control run with modern ocean heat transports in a 65 meter mixed layer slab ocean model b08h is the standard Model II 8x10 workstation control run with modern ocean heat transports in a 65 meter mixed layer slab ocean model
