Abstract
Measurements of ozone at different altitudes between 440 m and 1445 m on a mountainside of the Swiss Alps were carried out in the summer 1988. Results showed that the ozone concentration at higher altitudes is greater than at the ground of the valley. Not only the average but the shorttime peaks were higher at 1442 m than at 440 m. Diurnal variation of the ozone was much higher at the ground of the valley than at the mountain site. Additionally nitrogen‐dioxide was measured at all sites with passive sampling tubes. A drastic decrease with height was observed.
