NSF/NCAR C-130 3V-CPI Raw 2D-S Imagery [Rogers/NCAR-RAF]
https://data.eol.ucar.edu/dataset/350.007

Summary
The Three-View Cloud Particle Imager (3V-CPI) is a combination of three
imaging instruments. Two of them comprise a 2D-S instrument, in which two 2D
probes image particles as they pass through beams that are oriented
orthogonally to each other and the airflow. If particles also lie in the
intersection of the sensitive areas of the two beams, they are seen by both 2D
probes. In that case, the CPI is triggered to take a high-resolution picture,
via a briefly illuminated high-resolution imaging array, to provide a third
image at high resolution. The probe is particularly suited to imaging ice
crystals, but also provide good detection of other hydrometeors including
large cloud droplets, drizzle and small rain drops, and precipitation
particles. The 3V-CPI measures the size, shape and concentration of water
drops and ice particles in clouds in the size range of 15-250 µm. This dataset
contains 2D-S data collected by the 3V-CPI aboard the NSF/NCAR C130 N130AR
during the IDEAS-4 C130 project. The 2DS puts all flight data into 3 files,
and the size of these files depends on the amount of time in clouds.
