Fast 2D-S Imagery -- png format
https://data.eol.ucar.edu/dataset/638.029

Summary
A 2D-S instrument is a cloud particle probe that contains two orthogonal open
path optical array probes, which image cloud particles between about 10
microns - 2 mm in size as they pass through the instrument sample volume. This
imagery is used to calculate the concentration and cross-sectional area size
distributions, and to estimate the mass size distribution of the observed
cloud particles. These variables are integrated across the size bins to obtain
the total concentration, extinction, and estimated total water content over
the observed size range. The particle imagery can be utilized to infer cloud
particle phase. This data does not cover the full size range of cloud
particles, and should be analyzed in conjunction with complementary cloud
probes, such as the CDP, HVPS, etc. This dataset contains Fast 2D-S imagery in
png format collected aboard the NCAR C-130 during the CAESAR project. The
images have been combined into hour long tarfiles running from zero minutes
zero seconds to 59 minutes 59 seconds after each hour. Note that the first and
last tarfile for each flight will contain less than a full hour of imagery.
Directory files returned with each order give the contents of each
corresponding tar file.
