Abstract

The article is devoted to the study of micro- and macrophysical characteristics of clouds and radiative effect according to the operational and experimental schemes of cloud-radiation interaction of the COSMO mesoscale model and ground-based measurements at the Meteorological Observatory in Lindenberg (Germany). Statistically significant deviations of the model cloud characteristics from the measurements are found. The probable reasons of ice cloud water content deviations in the upper troposphere are determined.
