Paper Abstract

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.
