Chandrasekar, Detection and Estimation of Reflectivity Gradients in the Radar Resolution Volume Using Multiparameter Radar Measurements, IEEE Transactions on Geoscience and Remote Sensing 37, no. 2 (March 1999): 1122-1127.http://hdl.handle.net/10217/68080Multiparameter radar measurements of rainfall, namely, reflectivity factor ZH, differential reflectivity ZDR, and specific differential phase KDP lie in a constrained three dimensional (3-D) space and therefore measurement of ZH, ZDR, or KDP should be consistent with the other two. This self-consistency relationship between ZH, ZDR, and KDP is valid when the radar resolution volume is homogeneous. When there are reflectivity gradients within the radar resolution cell, the self-consistency relation is perturbed. This perturbation can be utilized to detect the presence of gradients in the radar resolution volume. This paper presents a technique to detect and estimate reflectivity gradients in the resolution cell. The technique is evaluated using theoretical analysis as well as experimental data collected by the NCAR CP-2 radar. It is demonstrated that the presence of reflectivity gradients larger than a few decibels can be detected using the algorithm developed in this paper.born digitalarticleseng©1999 IEEE.Copyright and other restrictions may apply.
