University of Washington Ice-Liquid Discriminator single particle phase classifications and 1 Hz particle size distributions/heterogeneity estimate

This data set was generated using the University of Washington Ice-Liquid Discriminator (UWILD), a cloud particle phase classification data set based on observations from the Two-Dimensional Stereo (2D-S) probe. The raw data set consists of particle-by-particle classifications (ice, liquid, or not classified), for each particle imaged by the 2D-S. Also included is a 1-Hz aggregated product. This includes particle size distributions (separated by phase) and a measure of cloud sub-1 Hz heterogeneity. The data set clouds sampled during the Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study (SOCRATES) field campaign, where the 2D-S was flown aboard the NSF/National Center for Atmospheric Research (NCAR) Gulfstream V (G-V) aircraft.
