The clouds play a significant role in the atmosphere particularly in the determination of the radiant balance. Since their type, structure and height considerable influence the transmission, absorption and re-radiation of the IR radiation they are of great importance for the local meteorology and the global climatology. In small spatial scales (micro- and meso- ones) the clouds considerable change in space and time. The ECLIPS (Experimental Cloud Lidar Pilot Study) program in which our lidar group also takes part is well described. In general, the main purpose is a ground-based lidar observation of the clouds simultaneously with the NOAA 10 and NOAA 11 meteorological satellites overpassing the same areas to be performed. Essential lidar data are the recorded profiles from which the information about the clouds height, optical depth and vertical extinction can be derived. The experimental data required for the ECLIPS Phase II measurements were recorded during the period from 21 May to O9 July 1991 at 30 observations by 3 hours each i.e. 1 hour before and 1 hour after the NOAA 10 and NOAA 11 satellites overpasses. The lidar data are completed with certain meteorological information obtained by the conventional means. The presented experiment was conducted using triple- beam aerosol meteorological lidar developed at the Institute of Electronics of Bulgarian Academy of Sciences, which are well described previously.
