PIP
Precipitation and Imaging Probe

The Precipitation and Imaging Probe (PIP) is an airborne optical spectrometer manufactured by Droplet Measurement Technologies. It measures the size and shape of particles in the size range of 100-6200 μm. It provides 2-dimensional imagery with a pixel resolution of 100 μm. PIP operates at the 660 nm wavelength and has a typical sampling frequency of 1 second. It has a sample area of 260 mm x 6.2 mm and can operate at airspeeds of 10-200 meters per second.
