The GPM Ground Validation Rain Gauge Pairs MC3E V2 data measures the amount of fallen precipitation collected by tipping bucket rain gauges made by Met One Instruments, Inc. and Campbell Scientific Corp. Precipitation from each is collected to a resolution of 0.254 mm of liquid water for each bucket tip. These gauges record the rainfall at a 1-minute resolution. This data set has two types of files, the recorded rainfall value (mm) and a cubic-spline interpolated rain rate (mm/hr) produced using the method described in Wang, 2008. There are two rain gauges located on each station (A or B), each with their own set of data files. Data were collected from April 2011 through June 2011 as part of the GPM Ground Validation Mid-latitude Continental Convective Cloud Experiment (MC3E).
