The results of measurements in the atmospheric surface layer (up to 4 km) performed by the aerosol lidar included in the mobile lidar complex are presented. The map shows the lidar signal at three points on the E18 route. The measurements were carried out on April 23, August 16, and October 15 in 2019. A vertical color bar indicates the relative magnitude of the scattered laser signal. The larger the value, the greater the scattering, which means more aerosol.
