Dual polarization radar measurements of rainfall parameters are based on the assumption of a mean shape-size relationship of raindrops. This paper focuses on retrieving and interpreting the mean raindrop shape-size relation from polarimetric radar observations. A procedure to retrieve the drop shape-size relation that governs the polarimetric radar observations of reflectivity (Zh) differential reflectivity...
Information about the shape of raindrops is critical for the retrieval of rainfall rate from dual-polarization radar measurements. As described in the literature, the relation describing drop oblateness as a function of its equivolumetric diameter is nonlinear. There are several relations that express the shape-size dependence as a nonlinear fourth-order polynomial that has five coefficients or 5...
Rain microphisycs retrieval has been proposed and demonstrated mainly at S-band where attenuation effects are usually negligible. Recent advances in attenuation correction techniques enable rain microphisycs retrieval also using attenuating frequencies, such as X- and C-band. Most up to date attenuation correction methodologies are based on the use of a constraint represented by the total amount of...
