Surface ozone measurements are not sufficient to understand the mechanisms of ozone formation in the lower troposphere. In this study, we have used instruments from the QUALAIR station, located in Paris center, that can measure vertical profiles of ozone, atmospheric dynamics parameters, and integrated contents of NO2 in the lowermost troposphere. First, a statistical analysis, using four years of ground based ozone LIDAR measurements (2011-2014), is done to understand the mechanisms responsible for the vertical gradient and the seasonal cycle of ozone in Paris. Then, in order to better assess the influence of transport on the spatial and temporal evolution of ozone, we focus on the results obtained from an instrumental campaign, organized ...
