Quantitative use of C-band radar measurements of reflectivity ( ) and differential reflectivity ( dr) demands the use of accurate attenuation-correction procedures, especially in convective rain events. With the availability of differential phase measurements ( dp) with a dual-polarized radar, it is now possible to improve and stabilize attenuation-correction schemes over earlier schemes which ...

Past experiences with ERS and Topex/Poseidon altimeter data have shown that rain can significantly alter the quality of altimeter measurements (dynamic heights, significant wave heights, wind speed) [1][2][3][4]. Among all the different atmospheric phenomena which can affect the altimeter measurement, rain is one of the less well understood and at present no reliable correction can be made for ...

In this study, a framework is discussed to apply aidspace-borne dual-wavelength radar for the estimation of characteristic parameters of hydrometeors. The focus of our study is on the Global Precipitation Measurements (GPM) precipitation radar, a dual-wavelength radar that operates at Ku (13.8 GHz) and Ka (35 GHz) bands. As the droplet size distributions (DSD) of rain are expressed as the Gamma...
