Results are presented of complex study of the clouds during the modification works aiming to prevent precipitation. To estimate the modification effect, a new technique is presented based upon comparison of the IR-radiometer measurements data, from the Meteosat satellite, on radiation temperature of the clouds after modification and those in natural development cycle. It is shown that for the case under study, radiation temperature increase is observed in the pixel corresponding to the city in which precipitation should be prevented.
