Bewölkungskartierung über der Schweiz mit Wettersatellitenbildern und Bodenbeobachtungen

Abstract. In this paper a map of cloud cover of Switzerland is presented, which is based on satellite data and the observations made by meteorological ground stations. First, the way the spatial information of meteorological satellites (covering 1 year) combined with the observations of ground stations during a period of 30 years, and how this was done with the aid of a regressions model, is explained. With this method, efficient use of the combination of satellite and ground data was attempted.
Secondly, the new cloud map of Switzerland is discussed and then compared with the cloud map made by SCHUEPP (1978).
