Abstrakt:

This contribution is describing interesting attenuation events in 39 and 19 GHz frequency bands using the measurement of signal of satellite Alphasat in Prague. Rain rates at two sites were measured continuously. A table of highest measured attenuation is added and discussed including thought about the rain type. The highest recorded attenuation was A19=8.1dB (A39=23dB) in 19 (39) GHz frequency bands while rain rate was exceeding 20 mm/h. An original equation for frequency scaling was formulated in the form of A39=2,7 A19 + 2,5 [dB].
