EXPERIMENTAL DETERMINATION OF ATMOSPHERIC DISPERSION IN THE MESOSCALE BY TRACER AND TETROONS
On April 27, 1983 a long range diffusion experiment took place in the area of the Upper Rhine Valley between the cities of Karlsruhe and Mannheim. The experiment was performed jointly by the Joint Research Centre of Ispra and the Kernforschungszentrum Karlsruhe in the following manner: + tracking of tetroons by radar up to distances of 56 km; + release of the tracer SF-6 at a height of 100 m and downwind sampling up to source distances of 50 km; + meteorological measurements by a 200 m high tower and by radiosounding. The experimental data have been analyzed to provide horizontal and vertical dispersion parameters, plume trajectories, mixing heights, vertical velocities, turbulence intensities and oscillation periods of the tetroons. Finally the trajectories, provided in a Lagrangian manner by the tetroons, are compared to those calculated from fixed point wind data.
