NEXRAD (NEXt-generation RADar) is a network of 158 high-resolution Doppler radar systems that are
operated by the National Weather Service (NWS). Its technical name is WSR-88D. NEXRAD data provides
centralized meteorological information for the continental United States and selected overseas locations. The
maximum range of a single NEXRAD radar site is 250 nm. In addition to a wide array of services, the
NEXRAD network provides important information about severe weather and air traffic safety.
NEXRAD data is not real-time. The lapsed time between collection, processing, and dissemination of
NEXRAD images can be significant and may not reflect the current radar synopsis. Due to the inherent delays
and the relative age of the data, it should be used for long-range planning purposes only. Never use NEXRAD
data or any radar data to penetrate hazardous weather. Rather, use it in an early-warning capacity of pre-
departure and enroute evaluation.
