A N2-Raman lidar on board ULA for Arctic atmospheric studies
International audience A key scientific question relative to atmospheric studies in the Arctic is the quantification and the vertical distribution of aerosols and their interactions with clouds in the lower troposphere.In May 2016, as part of the PARCS (Pollution in the ARCtic System) project, we wi...
