Abstract

The paper presents new results of measurements of the vertical derivative of the average temperature and the average horizontal wind speed of the turbulent atmosphere in the mountain boundary layer. The measurements were made in July-August 2019 in the mountainous area of the Sayan solar Observatory. These measurements are a continuation of previous research by the authors of the article, devoted to the experimental study of spatial derivatives of the average characteristics of atmospheric turbulence over the territories of mountain observatories. For measurements the new mobile hardware-software ultrasonic complex AMK-03-4 designed to measure statistical characteristics of different meteorological fields in turbulent atmosphere and their spatial derivatives was used. In this paper, a new improved algorithm for determining and eliminating systematic errors in calculating derivatives from the obtained experimental data is proposed.
