Abstract

Cloud condition measurements were carried out in the period from 29 May 1991 to 29 June 1991 at Obninsk lidar station. The lidar, operating daily at the wavelength of 532 nm over 24 days from 2.5 to 4.5 h., when NOAA satellites overpassed Obninsk, where the measurements of outgoing infrared irradiance flows were carried out. The overall duration of the measurements is 55 h. According to laser sounding results computations were carried out at the height of the cloud bases, the top of clouds, and the optical thickness of clouds (in those cases when it was possible to do).
