On the control of mid-latitude stratospheric aerosol budget from 23-year series of Haute-Provence lidar and global satellite observations
Résumé
The paper presents new high-quality stratospheric aerosol observations spanning 1994-2016 at Haute-Provence observatory (OHP, 44 °N, 6 °E) obtained by two independent lidar systems. Lidar series are analyzed together with global observations by CALIOP and other satellite sounders to characterize the variability and evolution of the mid-latitude stratospheric aerosol over the last two decades. Volcanic contributions and factors controlling the non-volcanic component of aerosol are discussed.
