neXraD
NEXRAD (NEXt-generation RADar), is a network of multiple high-resolution Doppler
radar sites that are operated by the National Weather Service (NWS). 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.
