A method for estimating rain rate and drop size distribution from polarimetric radar measurements

  journal={IEEE Trans. Geoscience and Remote Sensing},
Polarimetric radar measurements are sensitive to the size, shape and orientation of raindrops and provide information about drop size distribution (DSD), canting angle distribution and rain rate. In this paper, we propose and demonstrate a method for retrieving DSD parameters for calculating rain rate and the characteristic particle size. The DSD is assumed to be a Gamma distribution and the governing parameters are retrieved from radar measurements: reflectivity ( ), differential reflectivity… CONTINUE READING
