Abstract. Airborne lidar and in-situ measurements of the aerosol properties were conducted between Svalbard Island and Scandinavia in April 2008. Evidence of aerosol trans-port from Europe and Asia is given. The analysis of the aerosol optical properties based on a multiwavelength li-dar (355, 532,...

| Summary: | Abstract. Airborne lidar and in-situ measurements of the aerosol properties were conducted between Svalbard Island and Scandinavia in April 2008. Evidence of aerosol trans-port from Europe and Asia is given. The analysis of the aerosol optical properties based on a multiwavelength li-dar (355, 532, 1064 nm) including volume depolarization at 355 nm aims at distinguishing the role of the different aerosol sources (Siberian wild fires, Eastern Asia and European an-thropogenic emissions). Combining, first aircraft measure-ments, second FLEXPART simulations with a calculation of the PBL air fraction originating from the three different mid-latitude source regions, and third level-2 CALIPSO data products (i.e. backscatter coefficient 532 nm,volume depolar-ization and color ratio between 1064 and 532 nm in aerosol layers) along the transport pathways, appears a valuable ap- |
