|Abstract:||A new method is developed to estimate the total cloud amount from GMS imagery databy the Two-Threshold-Method (TTM) taking account of the spectral peaks due to the groundsurface and of the pixels totally covered by cloud. The approximate agreement is obtainedbetween the estimated values and the ground-observed cloud amounts over an area of about10 4 km2. The possibility of classification of cloud types from GMS IR data into low, middle, high and convective clouds is studied and found that they can be distinguished from each otherby TBB spectral parameters except the middle and convective clouds.|
