Monthly Mean Composites of CCM3 output

bulletPlot seasonal composites (averages) of the mean or anomalies from the CCM3 runs. There are 12 runs each that were forced using observed tropical SST fields and observed global SST fields. Variables are available from Jan 1950 to Dec 1999.

bulletInformation on the CCM3 project, how to reference the dataset and how to get the data can be found at the NCAR CCM3 page. More information on the model runs themselves can be found here. Values below the surface are set to missing.

Enter Years for composites (from 1 to 16) e.g. 1972. For seasons that span a year (e.g. DJF), please enter year of the LAST month.

To subtract one set of years from another, use a minus sign (-) before the years that are to be subtracted.
