XM NEXRAD
WSR-88D, or NEXRAD (NEXt-generation RADar), is a network of 158 high-
resolution Doppler radar systems 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. The NEXRAD network provides
important information about severe weather for 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. Instead, use it
in an early-warning capacity of pre-departure and en route evaluation.
