Abstract
A specialized aerosol lidar has been designed at Institute of Atmospheric Optics SB RAS for remote sounding of atmospheric turbulence. The lidar records aerosol backscattering amplification (BSA) in the turbulent atmosphere. An image jitter sensor (IJS) was manufactured for automated monitoring of turbulence along a path; it allows estimation of the mean intensity of atmospheric temperature turbulence along a horizontal 2-km path. The results of simultaneous operation of BSA-2 lidar and IJS under weak atmospheric turbulence are described. They were used for estimation of the turbulent lidar sensitivity. It was noted that IJS readings of the variance of image jitter differ in horizontal and vertical directions under a weak turbulence. An increase in the vertical component of the jitter variance was caused by some slow atmospheric processes or convection near an IJS target, which did not affect the lidar data.
