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

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
