Symposium on the Tropospheric Chemistry of the Antarctic Region: Pre- Conference Abstracts
Abstract
At present, lidar techniques are successfully used to study tropospheric aerosols. Lidar systems help to understand dynamic processes in the atmosphere. This paper describes the lidar systems used to study the tropospheric aerosols and gas composition of the atmosphere, aerosol and humidity distribution in the atmospheric underlayer over the ocean and experimental measurements of CO2 concentrations. Two wavelengths were used to sound aerosols. Lidar systems installed on a research vessel helped to resolve aerosol concentration profiles up to 10 km and water vapor concentration profiles up to 1.5 km in height. Stationary coastal lidar ensured the height of aerosol sounding up to 30 km. In the atmosphere/ocean interlayer, the height distribution of aerosol concentrations and humidity fields for various meteorological situations has been studied. The data are obtained for the inverse humidity layers formed 100-300 m over the ocean which cause the formation of aerosol layers with greater concentration.
