Description
Various measurement techniques have been deployed for the monitoring of ozone vertical distribution at Haute-Provence Observatory (44°N, 6°E) within the Network for the Detection of Atmospheric Composition Changes (NDACC) since the 1980s. These techniques include ozone lidars, balloon soundings and Dobson Umkehr measurements. This presentation will review the performance of the various experimental techniques deployed at OHP in terms of long-term trend evaluation, with a particular focus on the recovery period starting at the end of the nineties. Comparisons with long-term time series obtained at nearby stations in the so-called NDACC Alpine station and with satellite data will be performed. Regarding trend evaluation, the main factors explaining the recent evolution of ozone, as a function of altitude, will be documented.
