Abstract

Between 2011 and 2017 complex experiments on lidar sounding of the atmosphere were conducted on the territory of Akademgorodok (Tomsk, 56°28'N, 85°E), accompanied by the launch of meteorological balloons. A total of 45 radiosonde sessions were conducted using Vaisala R92SGP radiosondes in the daytime and at night. WE compared the vertical moisture profiles and the profiles of backscattering coefficient. In most cases aerosol layers are present at altitudes where a local increase in relative humidity is observed. However, in 10 cases out of 45, the location of the aerosol layers on the records does not coincide with the position of the wet layers. The report provides several examples of such records, discusses the possible conditions for the occurrence of such phenomena.
