Arctic aerosol and cloud measurements in the frame of the Ice-Atmosphere-Ocean Observing System (IAOOS) project

摘要: In the frame of French IAOOS Equipex project, a new observational network is to be developed for ocean-ice-atmosphere survey over Arctic starting in 2015 better understand interactions and particular role aerosols clouds Arctic. Eye-safe lidar measurements will allow profile atmospheric part, with objective perform regular characterize their vertical structure optical properties complementing satellite observations. Radiation meteorological parameters simultaneously measured at surface. A first buoy has been prototyped deployed April 2014 Barneo site set by Russian teams North Pole. Measurements autonomous backscatter ever arctic have taken from end November before was lost. second data were acquired during N-ICE campaign north Svalbard winter 2015. Up four profiles day (10 mn sequence each) performed allowing good sampling respect analyses. Observations shown that occurrence low level higher than 90% summer. New deployments are planned summer as start network. The project presented, instruments described results discussed.
