The TRANSALP 90 Campaign : The Second Tracer Release Experiment in a Sub-Alpine Valley
An experimental tracer release campaign took place in the Ticino river valley, Switzerland, aimed at understanding the air mass exchanges across the Alps. This exercise was the second of a number of experiments in which simple valley breeze and subsequent drainage flow conditions were selected in a single valley. An extended meterological network was det up during the campaign. A part from the synoptic observations, meteorological data were gathered using a number of supplementary ground stations and a sonic anemometer. Temperature profiles are available, and wind and turbulence profiles are available through 3 Doppler acoustic sounders. An aircraft and a motor glider produced consistent information on the wind, temperature and humidity structure of the atmosphere above the area of the experiment.
