Aerosol structure measurements in the troposphere were carried out at the Arctic Lidar Observatory for Middle Atmosphere Research (ALOMAR), Norway, during summer 2007. ALOMAR troposheric lidar and Cimel CE-318 sun photometer were used to implement the aerosol measurements. Three wavelengths of the sounding laser radiation were used during the experiment λ₁=1064nm, λ₂=532nm and λ₃=355nm which brings additional information about atmospheric aerosol optical and microphysical characteristics in the whole troposphere. The experimental data could be arranged in two groups: days when Ci-clouds were observed (in June) and days when the meteorological situation is characterized with clear sunny weather (in the beginning of July). In days with presence of Ci-clouds two layers are observed in the planetary boundary layer-the first one with maximum height from 1500m to 2000m; the second one with maximum height from 2000m to 3000m. In clear sunny days few layers are observed with minimum height from 1500m to 2300m and maximum height around H=6000m. The height of the layers remains constant or decrease with time. The lidar data are juxtaposed with the data obtained by the sun photometer.
