Global Hydrology Resource Center (GHRC) has published the dataset GPM Ground Validation Met One Rain Gauge Pairs IFloodS. Twenty-five tipping bucket rain gauge pairs were deployed during the Global Precipitation Measurement (GPM) Ground Validation (GV) Iowa Flood Studies (IFloodS) mission, which took place in Iowa during April-June 2013. Along with the disdrometers these rain gauges provided an additional means for directly measuring rainfall during the campaign. Two different models of these rain gauges, which are manufactured by MetOne Instruments, Inc., were used. The Model 380 gauges have a 30.5 cm diameter catchment funnel and a resolution of 0.2 mm of liquid water for each tip. The Model 370 gauges have a 20.3 cm diameter catchment funnel and a resolution of 0.01 inches.
