The GPM Ground Validation Cloud Spectrometer and Impactor (CIP) LPVEx dataset provides particle size spectra for the Global Precipitation Measurement (GPM) Misson Ground Validation Experiment. Data was collected by the Cloud spectrometer and impactor (CIP) and 2D-S (2-dimensional stereo probe) aboard the University of Wyoming King Air flown in Finland during the Light Precipitation Validation Experiment (LPVEx) from August to October 2010. Lat, lon, altitude, pressure, and temperature are provided with the total concentration of particles with diameter greater than 100 microns.
