The mechanics of air mass exchange between stratosphere and troposphere, and the controlling factors were studied. The cosmogenic radionuclides /sup 7/Be, /sup 32/P, /sup 33/P, and /sup 35/S serve as tracers. Their variation in time is observed from aerosol samples obtained on a daily basis above the boundary layer. Processes of transport are determined by isentropic trajectory analysis. An analysis of a long-term period of days for which continuously daily trajectory analyses are determined is presently underway. Moreover, in the present report a method is described permitting the forecasting of stratospheric intrusions by monitoring the relative humidity in the upper and middle troposphere. Forecasting accuracy is apparent from a test. The Lidar system has been completed so far as that remote aerosol sensing of aerosol layers in the lower stratosphere is now possible up to 30 km altitude. An example will demonstrate the measuring technique. Measurements of the ozone distribution in the boundary layer (3 measuring sites between 3000 and 700 m a.s.l.) and of the atmospheric total ozone content are presently started and will be integrated into the current program. Based on a comprehensive data material (1969-1975) we studied for the first time the multifarious interactions between solar-terrestrial events and the stratospheric-tropospheric exchange.
