Lidar signatures of volcanic and biomass burning aerosols after long-range transport at the french antarctic base Dumont d'Urville
International audience In the frame of the NDACC (Network for Atmospheric Composition Changes), lidar time series are routinely acquired at the french antarctic base Dumont d'Urville. Aerosol and cloud profiles are monitored using a 532nm backscatter and depolarization stratospheric lidar syste...
