4. METHODS
DESCRIPTION OF THE EXPERIMENTAL SET-UP USED - The atmospheric dispersion process was investigated by carrying out SF6 tracer experiments. The tracer was released about 6m above ground level near the Goesgen meteo tower. Sampling units were placed on ellipses around the release point. Total sampling time was at least one hour. Tracer concentrations were determined after each experiment by gaschromatography.

14. DESCRIPTION OF EXPERIMENT AND ANALYSIS
To investigate the flow field in the test region, the following measuring setups were used: (1) Three tethered balloon sounding systems to measure temperature, humidity, wind speed and direction; (2) a meteo tower to measure 10-minute averages of wind direction and velocity at two fixed heights; (3) sonic anemometers to measure heat flux, friction velocity, Monin-Obukhov length, and wind speed at the release point and at a certain distance; (4) 2-m masts to measure wind speed and direction continuously. The wind flow system was measured by radar-tracked tetroons.
