The GPM Ground Validation Rain Gauges NASA ACHIEVE IPHEx dataset was gathered during the GPM Ground Validation Integrated Precipitation and Hydrology Experiment (IPHEx) in North Carolina from May 9, 2014 through June 14, 2014. This dataset includes data from the Optical Scientific Optical Rain Gauge instrument and Novalynx Tipping Bucket Rain Gauge instrument which are both part of the NASA Goddard Space Flight Center (GSFC) ACHIEVE ground-based mobile laboratory. The optical rain gauge obtains high sensitivity optical measurements for precipitation rate and quantity, as well as measures 24-hour cumulative precipitation, precipitation rate, and temperature. The tipping bucket rain gauge is a standard tipping bucket rain gauge that measures 24-hour cumulative precipitation. Data files are available in netCDF-3 format.
