Procedures for estimating rainfall attenuation along radiowave paths from radar reflectivity measurements alone have been shown to be of limited value without additional information such as ground-based disdrometer measurement or dual polarization radar measurements, e. g. , differential reflectivity. The latter radar parameter is used to derive a new dual wavelength signal h, which accounts for attenuation in rainfall and should be useful for detecting the presence of non-rain hydrometeors as well as hail.
