Experimental studies of vertical profiles of the extinction coefficient of Ci-clouds in the visible spectral range with the help of a ground lidar are discussed in the present paper. The shape of the extinction coefficient profiles is found to differ for clouds with different lower boundary heights. Empirical correlations are obtained which describe the dependence of the extinction coefficient of Ci-clouds in the visible range on height.
