Results are presented on the measurements of attenuation observed during a period of 33 months with a 20 GHz solar radiometer located in the neighborhood of Paris. Obstacles associated with the use of radiometry are examined to derive statistical information applicable to an earth/satellite link. It is shown that the distribution of attenuations observed by a solar radiometer may significantly differ from that which would be observed on the earth/satellite path. An attenuation correction method is proposed which permits evaluating the effect of site angle on attenuation and determining the height of relevant precipitation. Nighttime measurements of the noise temperature of the sky at the zenith are used to show that the upper limit of precipitation is practically constant and is about 3 km. The correction of the curves representing the distribution of observed attenuations is discussed.
