CIS-LiNet lidar network has been established by lidar teams from Belarus, Russia, and Kyrgyz Republic. Its objective is carrying out coordinated lidar observations on the territory from Minsk to Vladivostok in cooperation with the observations under EARLINET, AD-Net, and AERONET Programs. All stations will carry out aerosol observations in the troposphere and stratosphere. Two stations in Minsk and Tomsk will implement ozone sounding in the stratospheric layer. Regular measurements of aerosol parameters are carried out in combination with radiometric observations. Joint analysis of air mass transfer trajectories and observation data is used for estimating impact of long-range transfer processes on the aerosol parameters.
