Joss-Waldvogel Disdrometer

The Joss-Waldvogel Disdrometer (JW Disdrometer) is an impact-type disdrometer developed by Distromet. This disdrometer calculates the size and distribution of hydrometeors by converting the momentum of falling raindrops into an electrical pulse. The amplitude of the pulse is correlated with the diameter of the raindrop. Raindrops in the range of 0.3mm and 5.5mm are able to be detected by the instrument. The JW Disdrometer contains both a sensor, which captures the falling raindrops, and a processor, which digitizes the signal provided by the sensor.
