Abstract :
It was discovered from measurements of the thermal radio emission from oil films on water at wavelengths of 0.23 and 0.8 cm that the quasi-periodical dependence of the brightness temperature on the film depth disappears after the first rain. The effect can be related to the phase decorrelation of thermal emission because of scattering on water droplets or on random dielectric heterogeneities in the oil-water emulsion
