GridRad-Severe - Three-Dimensional Gridded NEXRAD WSR-88D Radar Data for Severe Events

5-minute event-based volumes of radar reflectivity, differential reflectivity, specific differential phase, correlation coefficient, velocity spectrum width, azimuthal shear, and radial divergence data. This data encompasses ~100 of the most severe events in the US each year based on tornadoes, hail, and wind from 2010 to the Present, with domains that vary to encompass each event. The storm track data are included for each of the events.

Data for 2010-2012 do not include differential reflectivity, specific differential phase, and correlation coefficient, which are only observed following the dual-polarization upgrade to the NEXRAD network that was completed in early 2013.
