Abstract:

Spectral and polarimetric signatures of echoes, obtained with a vertically pointing millimeter wave radar, are examined with regard of their potential to retrieve range resolved microphysical characteristics of clouds, including the detection of mixed phases. A novel target classification algorithm based on this information was applied to deep frontal clouds. Examples of spectral/polarimetric profiles are shown to illustrate the retrieval technique, and first findings on microphysical structures and dynamics of such cloud systems are presented.

Spektrale und polarimetrische Signaturen von Echos, die man mit einem vertikal gerichteten Millimeterwellen Radar erhält, werden in Hinblick auf die Möglichkeiten untersucht, hieraus höhenaufgelöste mikrophysikalische Wolkeneigenschaften einschließlich der Detektierung gemischter Phasen abzuleiten. Ein neuer Zielklassifizierungs-Algorithmus, der diese Signaturen nutzt, wurde auf hochreichende frontale Wolken angewendet. An Hand von Beispielen spektral/polarimetrischer Profile werden die Retrieval-Technik und erste Ergebnisse zu mikrophysikalischen Strukturen und der Dynamik solcher Wolkensysteme gezeigt.
