Abstract (English):
The paper presents the results of testing the optical-electronic unit of the LRV-2 lidar. It is shown that the radial velocity estimates obtained by the LRV-2 lidar during vertical sounding can be used to estimate the kinetic energy dissipation rate using the vertical velocity spectral density method. The correlation coefficient between the time steps of the estimates of dissipation rates obtained by the LRV-2 and Stream Line lidars at a good signal level during the daytime exceeds 0.9.
