Abstract : Models of rain intensity along an aircraft glide slope are derived for the purpose of comparing attenuation losses at various radar frequencies. The models are intended to protray a rain intensity over a 10-minute period and 10-mile or 20-mile ground track. The rain intensities are selected to represent rates which would occur less than one percent or 0.1 percent of the time during the rainy season at the rainiest airfield in the U.S. and the rainiest airfield (with over 5000 feet of paved runway) in the world.
