Abstract :
Recent radar polarimetric observations of mesoscale convective systems typical for Oklahoma indicate unexpectedly large attenuation of the 11-cm wavelength radiation. This leads to large errors in conventional radar rain estimates. Differential phase polarimetric measurements are immune to attenuation and, thus, are indispensable in such situations. An independent assessment of precipitation using rain gauges substantiates the superior quality of polarimetric estimates of heavy rain for the analyzed storms
