Webdifferential reflectivity {ZDR) technique of Seliga and Bringi (1976) which provides a means of estimating rainfall rate (R) by combining measurements of radar reflectivity factors at horizontal (ZH) and vertical (Zv) polarizations; ZDR (dB) is defined as the ratio of these reflectivities, i.e., ZDR = 10 log (ZHIZV). Results from WebAlso, higher differential reflectivity (ZDR) values were measured with large aggregates due to the Mie resonance effect, lower fluttering angles, or induced field transverse. Data from the three sites were used to develop S(ZeH)-based algorithms at 1 hr interval SWE, where ZeH is the radar equivalent reflectivity factor. http://weather.ou.edu/~scavallo/classes/metr_4491_5491/DualPol.OnePager.pdf ticketek ed sheeran sydney
