Northern Foehn and Ground-Level Ozone at Ispra

HIGH OZONE CONCENTRATIONS IN TROPOSPHERIC AIR ARE MAINLY RELATED TO PHOTOCHEMICAL PROCESSES OF ANTHROPOGENIC IMMISSION ON THE LOCAL OR REGIONAL SCALE. IN THE PREALPINE REGION, COMPARABLE LEVELS MAY BE REACHED DURING FOEHN EVENTS BECAUSE OF THE INJECTION OF OZONE FROM THE UPPER LAYER. FROM THE ANALYSIS OF FOEHN EPISODES DURING 1988 AT ISPRA, WHERE AN EMEP STATION AND A METEOROLOGICAL OBSERVATORY ARE IN OPERATION, WE HAVE BEEN ABLE TO CLASSIFY THE DIFFERENT CASES. A CORRELATION BETWEEN THE WIND SPEED AND THE OZONE CONCENTRATION IS SHOWN.
