Next Generation Weather Radar (NEXRAD) makes conventional reflectivity observations and also uses the "Doppler effect" to measure motion of clear air and atmospheric phenomena within storms. The maximum range of NEXRAD is 230 kilometers (125 nautical miles). Although NEXRAD is land-based, there is some radar coverage offshore. The greatest offshore coverage is along the Atlantic and Gulf coasts.
