Instrument

2DVD
Two-Dimensional Video Disdrometer

The Two-Dimensional Video Disdrometer (2DVD) is a stationary, ground-based optical disdrometer. It features two line-scan cameras that continuously measure various precipitation properties such as droplet shape, fall velocity, and size distribution. The 2DVD accurately measures all precipitation particles with a diameter greater than 0.2 mm, making it ideal for different precipitation studies.
