Low-Altitude Sensing of Urban Atmospheric Turbulence with UAV

Abstract: The capabilities of a quadcopter in the hover mode for low-altitude sensing of atmospheric turbulence with high spatial resolution in urban areas characterized by complex orography are investigated. The studies were carried out in different seasons (winter, spring, summer, and fall), and the quadcopter hovered in the immediate vicinity of ultrasonic weather stations. The DJI Phantom 4 Pro quadcopter and AMK-03 ultrasonic weather stations installed in different places of the studied territory were used in the e… Show more

“…Technicians may take multiple altitude readings during ight and cross-reference them to ensure accuracy. In instances where altitude readings deviate signi cantly from the expected range, a UAV operator with expertise in altitude control may be consulted or an automated alert system triggered to investigate and rectify the issue promptly [11].…”

“…The latter wind sensing technique can be adapted for various ascent rates and could also prove useful for measuring wind uctuations required to infer atmospheric turbulence. [25][26][27] Rigid body models have been used to estimate wind velocity in the lower atmosphere ascending at various rates. 25 Efforts to explore the feasibility of employing multirotor sUAS wind sensing capabilities for resolving atmospheric ow variations in aquatic environments are just beginning.…”

“…The development of these standards requires the use of modern methods for diagnosing turbulent vortex formations. An analysis of the existing diagnostic methods shows [3] that in the height range needed for low-altitude sensing (up to 500 m), there are no instruments that can be used for UAV navigation under adverse meteorological conditions and that have a unique characteristic in terms of high spatiotemporal resolution. For example, sodars, radars, and lidars [4][5][6][7][8][9] can provide spatial resolution from tens to hundreds of meters.…”
