The radars operate unattended according to selected scanning patterns, and radar data (reflectivity, mean radial velocity, and Doppler spectral width) and products derived from these data are disseminated to offices of the National Weather Service (NWS)

network comprises 45 Doppler weather radars deployed at major commercial airports near medium-to-large-sized US cities with greatest wind-shear risk. This system addresses the FAA's requirement for surveillance of weather close to airports with higher sensitivity and faster updates than can be provided by the WSR-88D system (Whiton et al., 1998)

From page 11... ...
The system is jointly owned by the NWS, DOD, and FAA, and each of these agencies established criteria for siting the radars based on factors including population distribution, climatology, approach and travel directions of severe weather, locations of airports and airways, and the location of NWS forecast offices and highpriority military and civilian facilities. The radars in the WSR-88D network, like those in the TDWR and ARSR networks, are long-range (> 400 km)

down to near-ground level, where damaging storm features such as tornadoes, hail, and downbursts impact both the public and low-flying aircraft. The Weather Service Modernization Act of 1992 established a criterion that the network should provide complete coverage over the CONUS at a height of 3.05 km (10,000 ft.)
