Some results on the ozone vertical distribution in atmospheric boundary layer from LIDAR and surface measurements over the Kamienczyk Valley, Poland

In this study, measurements of the vertical and temporal variations in ozone concentrations over the mountainous area during three observation periods in July 1997 and August 1998. The data used in this study were obtained from a differential measurement technique called Differential Absorption Lidar (DIAL) and from the ground-based stations at different altitudes. Many ozone profiles exhibited distinct local maxima up to 100 ppb and a large variation in mixing ratios existing in the height range between 1150–1650 m a.s.l. Ozone levels have more than doubled at about 1340 m a.s.l. as compared to higher altitudes.
