Particle Size Distribution (PSD) Data
Summary
This data set consists of data collected from two instruments on the NASA DC-8 aircraft from the High Ice Water Content (HIWC) Radar study that took place in Fort Lauderdale, Florida; Palmdale, California; and Kona, Hawaii. These data are from the DMT Precipitation Imaging Probe (PIP), and the SPEC Two-Dimensional Stereo probe (2D-S). Both instruments are two-dimensional optical array probes which record images of particles that travel through their sampling area. The recorded images are then analyzed to produce particle size distributions from 50 microns to 3 centimeters in diameter. The data files consist of data in txt files, and images in png format. The images are contained in tar files by flight.
