Drop size distribution (GOP-3)

Observations of the rain drop size distribution (RDSD) with ground-based disdrometers and vertically pointing Micro Rain Radars (MRR) will be performed. At least 13 will be located at selected sites in order to study differences of RDSDs over flat terrain including maritime conditions on one hand and over orographically structured terrain on the other hand. A transect of MRRs will be deployed in the COPS area and coordinated with polarimetric radar (POLDIRAD/DLR) observations during COPS. Examples of actual MRR observations can be viewed here.

Different surface based disdrometers are used as well: 2 Joss Waldvogel disdrometer (JWD), 3 optical disdrometer ODM470, and 4 Parsivel disdrometers. These instruments are based on different physical principle and methods for retrieving DSDs and will thus help to keep the major uncertainty of MRR-based DSDs under control, namely a potential bias due to vertical wind.
