Abstract

The cloud field bottom was sounded in zenith direction by a single-channel IR radiometer which registers the downwelling thermal radiation in the spectral range 7.5 divided by 13 micrometers . The time dependence of the signal is related with the effective radiative temperature of the sounded cloud bottom. The registered records were statistically analyzed. The evaluated statistical characteristics of the signals were analyzed and compared with the information about the morphological structure of the corresponding clouds. It was proved that there exists relationship between the both types of cloud characteristics.
