摘要：The aim of this study is to determine the spatiotemporal
structure of the dispersion climate over Central Switzerland.
For that reason the investigations have been divided into two
parts. The first part deals with the analysis ofthe temperature
stratification which is an important indicator of the vertical
diffusion. It was carried out by using IR satellite data as well as
temperature measurements and fog observations. The second part is concemed with a detailed analysis of the wind
field. Measurements on more than 50 stations have been
temporally interpolated and compared with numerical simulations.
