Applications of Polarization-Diversity Radar and Lidar in Meteorology.

Abstract

Evaluation of several actual or potential applications of polarization-diversity radar and lidar technology are presented. These include: determination of thermodynamic phase, shape, size, and orientation of hydrometeors; determination of rainfall rate from differential reflectivity measurement; increased unambiguous velocity measurement by polarization coding of Doppler radar pulse pairs; measurement of propagation parameters; and selective suppression of meteorological and non-meteorological echoes. Evaluations include descriptions of demonstrated capabilities and identification of limiting factors associated with equipment design or meteorological parameters. Measurement capabilities and operational benefits of a coherent polarization-diversity radar are discussed. Prospects for the use of lidar in distinguishing high-altitude aerosol layers from clouds are described. (Author)
