Development of metrics for evaluating simulations of clouds, radiation, and precipitation for GCSS

PI: Crispian Batstone
Institution: National Oceanic and Atmospheric Administration
Additional Investigators: Robert Pincus
Abstract:
We plan to develop metrics for evaluating the simulation of clouds, radiation, and precipitation by global climate models. These metrics will be compact scalar scores which summarize the agreement of the simulations with observational datasets at a range of temporal and spatial scales. The scores are explicitly meant to be easy to compute from greatly reduced information (e.g. monthly means) and are intended to provide objective measures of climate model performance. We seek results from a range of models to use in developing these metrics.
