Abstract

To further a method for evaluating and analyzing parameterizations in climate general circulation models (GCMs), the US Department of Energy is funding a joint venture of its Climate Change Prediction Program (CCPP) and Atmospheric Radiation Measurement (ARM) Program: the CCPP-ARM Parameterization Testbed (CAPT). CAPT is not a panacea for improving climate GCM parameterizations at all time scales, but just one choice from a "tool kit" that may also include SCMs, CRMs, and simplified GCMs. Nonetheless, insights obtained from adopting this NWP-inspired methodology are expected to contribute significantly to the general improvement of GCM climate simulation.
