Summary: ALPTRAC-SNOWMET was the meteorological contribution to the EUROTRAC Subproject ALPTRAC and was conducted between 1990 and ~1996. ALPTRAC was concerned with the occurrence and deposition in the high Alps of aerosols and trace gases being responsible for the acid input. With respect to meteorology, source regions were determined by means of trajectories, and the mechanisms of transport of boundary layer air to the Alpine peaks were studied. These investigations are important for judging the representability of measurements at high-altitude stations. Foci of the investigations were the high- mountain observatories at Sonnblick (3106 m) and Jungfraujoch (3450 and 3576 m).

For a general overview of ALPTRAC, see the Final Report (published by Springer).
