Abstract

Investigation of Vertical Exchange Processes with Lidar A contribution to subproject TOR-2 W Carnuth, H Eisele, R Sladkovic and T. Trickl Fraunhofer-Institutfur Atmospharische Umweltforschung, Kreuzeckbahnstr. 19, D-82467 Garmisch-Partenkirchen, Germany The concentration of ozone and other trace gases in the free troposphere is to a major extent governed by vertical exchange of air with the neighbouring ranges of the atmosphere. Two of the most important vertical-exchange mechanisms, air input from the stratosphere and upward transport above mountains, have recently been studied in some detail by remote sensing with the IFU lidars as a contribution to the EU project VOTALP (Vertical Ozone Transport in the Alps) project. Some of the results are briefly summarised in the following. Between January 1996 and December 1997, the stationary ozone lidar took data during more than 40 intrusions of stratos
