JW Disdrometer
Joss-Waldvogel Disdrometer

The Joss-Waldvogel (JW) Disdrometer is a ground-based impact-type disdrometer manufactured by Distromet. It uses an electromechanical counter to determine the drop size distribution (DSD) of raindrops. It can detect raindrops within the 0.3 to 5.5 mm diameter size range. The JW Disdrometer can record up to 200 drops per second and has a typical sampling frequency of 1 minute.
