The world’s premier ground-based observations facility advancing atmospheric and climate research

2DS-AIR

The two-dimensional stereo probe (2D-S) is a cloud probe utilizing shadowgraphy to measure cloud drops and ice crystals in the size range from 25 µm -ca. 1 mm, and can detect even larger hydrometeors with less accuracy. The 2D-S provides two-dimensional shadow images of the hydrometeors that are scanned individually along the flight path.
