The WSR-88D, or the Next Generation Radar (NEXRAD), weather radar networkĬomprises 156 long-range Doppler radars sited on a grid covering the contiguous United National Weather Surveillance Radar Network (Z = radar reflectivity factor V = Doppler velocity W = spectrum width) Source: John Cho, Massachusetts Institute ofġ56 National grid S 8.5 m dia 750 kW 4-6 min Radars that comprise the WSR-88D, TDWR, ASR, and ARSR networks.

Be sure to check out these video tutorials and frequently asked questions to help you get started using the site. We added new features to the radar viewer based on feedback we received from the public and emergency management community. ![]() The webpage is more reliable now that it's on an operationally supported system 24/7. The new page’s infrastructure allows for easy integration of new datasets, like satellite imagery, in the future and Radar animation loops can be saved, shared and used on social media For times when a single radar is out of service, you still have coverage since radar beams overlap Ībility to customize data to any domain, and data layer preferences can be saved or bookmarked More radar data, including 159 NEXRAD Doppler radars and 45 Terminal Doppler Weather Radars.
