All types of telegrams contain cloud layer and associated penetration depths; in the advanced and raw data telegrams also the standard deviations of these values and aerosol
layers are transmitted. These values are displayed on the left side. The right side shows
the course of cloud heights over the last 120 (tbd) telegrams. . . . . . . . . . . . . . . . . 79
