Expansion and Enhancement of the Mesoscale Model Evaluation Testbed (MMET)
MMET provides initialization and observation data sets for several case studies and week-long extended periods that can be used by the entire NWP community for testing and evaluation. Over the past year, the case list has been expanded to include additional events of interest to both the research and operational communities (e.g., atmospheric river events, mesoscale convective system). The DTC also utilized the MMET data sets to provide baseline results to the NWP community for select operational configurations that use both the Weather Research and Forecasting Advanced Research WRF (WRF-ARW) and Nonhydrostatic Multiscale Model on the B-grid (NMMB). These data sets can be used to compare against updated versions of the model or for testing sensitivities to different physical and dynamical configurations in order to progressively improve the forecast performance. This presentation will highlight the results from these types of comparisons as well show baseline results from the newly expanded case list.
