The Multi-Year Reanalysis of Remotely Sensed Storms: A CONUS-wide, Multi-Radar, Multi-Sensor Climatological Database for Severe Weather Hazards

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. This presentation will focus on the applications of the severe weather-related products. These products include a maximum hail size estimate grid, reflectivity at various isothermal levels and estimations of storm rotation. These products can be used to produce a wide range of analyses including: radar-based climatologies of hail and reflectivity, storm tracking and extracting storm characteristics, verification for convection allowing models and evaluations of National Weather Service severe weather warning “goodness” beyond typical measures based simply upon whether or not a single severe weather report occurred within the boundaries of the warning. Discussions related to these applications, the status of the quality control efforts and the next steps for MYRORSS will all be included in this presentation.
