Innovative Evaluations of National Weather Service Severe Weather Warnings with a CONUS-wide Multi-Radar, Multi-Sensor Climatological Database

The Multi-Year Reanalysis of Remotely Sensed Storms (MYRORSS) is a joint-effort between OU/CIMMS, NCSU/CICS, NOAA's NSSL and NOAA's NCEI, to process the entire record of WSR-88D radar data for the contiguous United States through the multi-radar, multi-sensor (MRMS) framework. To date, the years 2000 through 2011 have been completed, with intensive quality control work continuing at CIMMS/NSSL. MYRORSS is split between two primary projects: hydrometeorology and severe weather. The severe weather products include a maximum hail size estimate grid, reflectivity at various isothermal levels and estimations of storm rotation. These products, combined with near-storm environmental information, population grids, storm reports, and other information, can provide innovative ways in exploring the quality and “goodness” of National Weather Service severe weather warnings. A summary of applications for the evaluations, extensions and additional data sets which could be used to further the evaluations and future work will be included.
