Instrument

2DVD
Two-Dimensional Video Disdrometer

The Two-Dimensional Video Disdrometer (2DVD) is a stationary, ground-based optical disdrometer. It has two line-scan cameras that continuously measure various precipitation properties such as 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 various precipitation studies.
