We report Sub-Arctic aerosol properties, obtained during three field campaigns conducted in 2005 and 2006. These have been carried out at the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR), Andøya Rocket Range, Norway (69°N, 16°E, 380 m asl), and were supported by the eARI (enhanced Access to Research Infrastructure) program of the European Union. The instruments used for this study are the ALOMAR tropospheric lidar and a Cimel sun photometer. Data in situ from cascade impactors is also included for better interpretation. Back trajectory analysis is presented. The evolution of the vertical distribution of the aerosols is analyzed, in order to study aerosol stratification and height patterns for long-range transported aerosols to this coastal Sub-Arctic site.
