Eureka, CA, USA NEXRAD/Gauge Site

A Next Generation Radar/Weather Surveillance Radar-88 Doppler (NEXRAD/WSR-88D) and a small rain gauge network in Eureka, California USA provided ground validation data for AMSR-E Rainfall Validation efforts. Gauges were installed 24-28 August 2000 in clusters of varying density to determine a best estimate of a true rain rate through measurement redundancy. The WSR-88D radar has a measurement range radius of 150-200 km. It measures instantaneous rain rate, stratiform/convective rain type, and five-day and monthly rain accumulation, in addition to radar reflectivity, with a 2 km resolution for most products.
