Abstract

It is well known that the processes of vertical propagation and dissipation of acoustic-gravity waves (AGWs) play an important role in the realization of connections between the dynamic processes in different layers of the atmosphere. This work presents the results of lidar probing of tropospheric aerosols, performed in Kaliningrad, Russia (54°N, 20 °E). The observations used a two-wave atmospheric lidar (with wavelengths of 532 and 1064 nm), which allows investigation of properties of troposphere up to the altitudes of 10-12 km. During the observations, the intensity of the lidar signal scattered in the troposphere was determined. Measurements that were carried out in the period of 2011–2018 that made it possible to determine the features of the vertical structure and the dynamics of aerosol particles. Analysis of the results of the observations revealed an increase of the wave activity in the troposphere during the periods of passage of the solar terminator in the range from 2 to 20 minutes.
