Instrument

2DVD
Two-Dimensional Video Disdrometer

The Two-Dimensional Video Disdrometer (2DVD) is a stationary, ground-based optical disdrometer. It uses two line-scan cameras to continuously measure precipitation properties, including droplet shape, fall velocity, and size distribution. The 2DVD precisely measures all precipitation particles larger than 0.2 mm in diameter, making it suitable for a wide range of precipitation studies.
