AIRCRAFT MEASUREMENTS OF VERTICAL VELOCITY AND WIND TURBULENCE PARAMETERS BY THE LRV-2 LIDAR DURING NADIR SOUNDING

The paper presents the results of measurements carried out using the LRV-2 lidar during nadir sounding from a flying aircraft. Based on the analysis of experimental data, altitude profiles of estimates of the vertical wind velocity dispersion and the turbulence energy dissipation rate up to a height of 1250-1600 meters were constructed. The data obtained indicate that the turbulent wind fluctuations over the Novosibirsk reservoir turned out to be significantly less intense than those observed over land. Also, when analyzing the sounding data near the cloud, it was possible to detect a velocity shift using one spectrum of the lidar signal, in which two Doppler peaks were present.
