Spatial Forecast Verification Methods Inter-Comparison Project

About the ICP

Recent advancements in weather forecasting and observational systems have created great improvements in resolution and prediction. However, use of standard verification practices often indicate poorer performance because, among other things, they are unable to account for small-scale noise or discriminate types of errors such as displacement in time and/or space (see papers in the references section). This issue has motivated recent research and development of many new verification techniques for handling spatial forecasts. The intent of this project is to compare the various newly proposed methods to give the user information about which methods are appropriate for which types of data, forecasts and desired forecast utility.
