Using objective comparisons of observed and simulated precipitation to help guide the improvement of Earth System Models
Abstract
In this presentation we discuss a community-based effort to establish the benchmarking of simulated precipitation in Earth System Models. We first summarize the impetus and outcomes of a recent workshop dedicated to the topic. This includes the identification of a tiered system of objective tests (metrics) for the following climatological characteristics: the mean state, seasonal cycle, variability across time scales, intensity/frequency distributions, extremes and drought. Preliminary results are shown gauging model performance changes across multiple generations of CMIP. The performance tests we describe are part of an open-source analysis framework being made available to model developers to help them make judgements about the quality of simulated precipitation during the model development process.
