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
