Conventional radars, used for atmospheric remote sensing, usually operate at a single polarization and frequency to estimate storm parameters such as rainfallrate and water content. </p><p style=&quot;line-height: 20px;&quot;> Because of the high variability of the drop size distribution conventional radars do not succeed in obtaining detailed information because they just use horizontal reflectivity. </p><p style=&quot;line-height: 20px;&quot;> The potentiality of the dual-polarized weather radar is investigated, in order to reject the ground-clutter, using differential reflectivity. </p><p style=&quot;line-height: 20px;&quot;> In this light, a radar meteorology campaign was conducted over the city of Rome (Italy), collecting measurements by the polarimetric Doppler radar Polar 55C and by a raingauge network. </p><p style=&quot;line-height: 20px;&quot;> The goodness of the results is tested by comparison of radar rainfall estimates with raingauges rainfall measurements.
