The Global Hydrology Resource Center (GHRC) released the GPM Ground Validation NCAR Cloud Microphysics Particle Probes GCPEx dataset containing data collected during the Global Precipitation Measurement (GPM) Cold-season Precipitation Experiment (GCPEX) for January and February 2012. Particle size distributions and particle image data, processed by NCAR, were obtained from the 2D-C Probe, the Cloud Imaging Probe (CIP) and the High Volume Precipitation Spectrometer (HVPS-3) carried aboard the University of North Dakota (UND) Cessna Citation aircraft. A related cloud microphysics dataset, GPM Ground Validation UND Citation Cloud Microphysics GCPEx is also available.
