Simultaneous measurements of precipitation using S-band and C-band polarimetric radars

摘要

Simultaneous measurements of heavy tropical rain made by closely located S- and C-band polarimetric radars are examined. The performance of different algorithms for rainfall estimation is discussed. It is demonstrated that the polarimetric algorithm based on the combined use of specific differential phase and differential reflectivity yields the least biased estimate of rainfall at S-band. Similar estimation at C-band faces challenges.
