Verification of Probabilistic Downscaling
Full verification is essential before the application of any downscaling model, particularly with a multifaceted approach. Climate downscaling is used in numerous applications, so many diverse verification methods should be utilized. We apply and adapt a multitude of forecast and distribution verification techniques to test the skill and representativeness of the daily-varying downscaled PDFs. Methods are used to assess the daily distributions, as well as the characteristics of randomly-sampled realizations. Examples of the best verification methods to use for specific applications of the data will be provided. Our downscaling is shown to be skillful across a variety of metrics for many aspects of the distribution, including the representation of extreme events. We also show that observed climatological statistics are accurately reproduced in the downscaled realizations.
