For rainfall with near-spherical drop shapes and constant drop density, the parameterization of V(bin) and M(bin) is chosen after Atlas and Ulbrich73. For the complex problem of snowfall Lempio70developed a common lump graupel parameterization based on the work of Hogan74, Brandeset al.75and...

Let us now assume a link geometry as depicted in Figure 6a, wherein the rain height hB is obtained either from a short-term forecast via WRF model or from an archive of historical data such as the MERRA. Thus, an estimate kˆ of the specific attenuation (in dB/km) is derived under...
