Description
Within the Network for the Detection of Atmospheric Composition Changes (NDACC), ozone total content and vertical distribution are monitored by various measurement techniques at Observatoire de Haute-Provence (44°N, 6°E) in Southern France. For the vertical distribution, these techniques include two ozone lidars for the measurement of stratospheric and tropospheric ozone vertical profiles, in situ ozone soundings and Dobson Umkehr measurements. For the total content, a Dobson and a SAOZ UV-Visible spectrometers have been implemented in 1983 and 1992 respectively. An intercomparaison campaign involving the NASA reference lidar (McGee et al.) was organized in July 2017 and March 2018 for the comparison of ozone and temperature vertical profile (Wing et al., 2020). Results of the campaign together with long-term comparison of ozone measurements with satellite measurements overpasses will be presented.
