- Abstract
The growing relevance of the use of unmanned aerial vehicles (UAVs) for studying turbulence in the atmospheric boundary layer (ABL) is associated with the need to obtain new observational data at different heights in the boundary layer, as well as over heterogeneous landscapes. Such new data is needed for developing turbulence models for spatially inhomogeneous and unsteady conditions. This paper describes the new Tsimlyanin UAV and its meteorological payload, developed specifically for studying the turbulent structure of the ABL. Tsimlyanin differs from similar vehicles by its hybrid scheme, which combines the possibility of vertical take-off and landing and horizontal flight in airplane mode. The meteorological payload includes specially designed measuring devices, namely, a multihole air pressure probe and a low-inertia resistance thermometer. Also, analog-to-digital converters for several sensors, as well as the onboard data-acquisition system, are newly developed. This paper presents the results of measurements carried out using the UAV during test flights in Tsimlyansk in August 2020. A good agreement between UAV observations with respect to vertical profiles of air temperature, wind speed and direction, dispersion of vertical speed with the data of observations of other complexes (acoustic anemometers, an automatic meteorological station, sodars, and a temperature profiler) was obtained. The results demonstrate the high potential of this UAV for studying turbulence in the ABL.
