2.5 The model evaluation tools - Recent updates

Fowler, Tressa L., John Halley Gotway, Randy Bullock, and Tara Jensen, National Center for Atmospheric Research

Model Evaluation Tools (MET) is a freely-available software package for forecast verification. It is distributed through the Developmental Testbed Center (DTC) for testing and evaluation of the Weather Research and Forecasting (WRF) model. Development has been led by the community: including WRF users, the DTC, and verification experts through workshops and user meetings. MET allows users to verify forecasts via traditional, neighborhood, and object-based methods. To account for the uncertainty associated with these measures, methods for estimating confidence intervals for the verification statistics are an integral part of MET.

Many features of the software were presented at the last workshop. However, the latest release includes many new capabilities including handling for GRIB2, MODIS, MADIS, little r, and SURFRAD data.  Ensemble handling capabilities have been extended. A whole new set of tools is available for tropical cyclone verification. Examples of the existing and new verification capabilities will be shown.
