| Zusammenfassung |
| The 2D-Video-Distrometer (2DVD) is a ground-based point-monitoring
precipitation gauge. From each particle reaching the measuring area front
and side contours as well as fall velocity and precise time stamp are
recorded. In 1991 the 2DVD development has been started to clarify
discrepancies found when comparing weather radar data analyses with
literature models. Then being manufactured in a small scale series the first
2DVD delivery took place in 1996, 10 years back from now. An overview on
present 2DVD features is given, and it is presented how the instrument was
continuously improved in the past ten years. Scientific merits of 2DVD
measurements are explained, including drop size readings without upper
limit, drop shape and orientation angle information, contours of solid and
melting particles, and an independent measurement of particles' fall
velocity also in mixed phase events. Plans for a next generation instrument
are described, by enhanced user-friendliness the unique data type shall be
opened to a wider user community. |
