Abstract :
Measurements are presented from eastern Canada of the polarisation-dependent ratio of microwave attenuation due to rainfall for vertical and horizontal linear polarisations, and of the frequency-dependent ratio of attenuation for a given polarisation. The exponent of the usual power law of frequency scaling of attenuation is 1.93±0.15 (SD) in the 11¿17 GHz frequency range.
