The GridRad data set consists of radar reflectivity data and radar
coverage information from 125 U.S. NEXRAD WSR-88D radars merged onto
a regular, three-dimensional, longitude-latitude-altitude grid at
hourly analysis intervals. Each analysis uses all available radar
azimuth scans within a specified time window centered on the
analysis time. The size of the time window is given in the files as
a global attribute. The data include weighted average radar
reflectivity from multiple observations, averaging weights, number
of azimuth scans (elevation angles) observing each volume, and the
number of azimuth scans (elevation angles) with echo in each volume.
Following conventional nomenclature, the NEXRAD volume scan files
are referred to as Level 2 data, while this gridded data are
referred to as Level 3 data.
