Twenty-five tipping bucket rain gauge pairs were deployed during the Global Precipitation Measurement (GPM) Ground Validation (GV) Iowa Flood Studies (IFloodS) mission taking 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. The Model 380 Precipitation Gauge, which is manufactured by MetOne Instruments, Inc., was 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.
