Raindrop size distributions derived from dual-polarization radar data have been used to model attenuation in the rain region of slant paths. Attenuation ratios for 14.455/11.786 GHz, 17.5/11.786 GHz, and 30.0/20.0 GHz have been derived and have been shown to be sensitive to both type of rain and assumed water temperature. An error analysis has shown the dual-polarization (copolar linear) technique to give a good prediction of attenuation ratios for all but very light rain.
