Abstract
cloudness leads to the variations f NNW attenuation in atmosphere nickness and brings difficulties during radio-astronomical neasure- nents. It Is advantageous to evaluate .*:hem using the derived dependence with radio-brightness temperature variations. Under cloudy atmosphere conditions there were carried out in :AM-Wave band the measurements of radio-brightness temperature variations that gave the opportunity to evaluate variations of attenuation, on their basis. As follows from the obtained r.m.s. values of attenuation variations and their temporal correian intervals, the usage of adaptive receiving makes it ?ossible to reduce attenuation variations and thereby to Increase the :.1---1co of radio-astronomical observations.
