Abstract:

The observation of the atmospheric boundary layer (ABL) using rotorcraft Unmanned Aerial Vehicle (UAV) can provide a new approach with high temporal and spatial analysis ability for studying the vertical structure of meteorological elements and atmospheric pollutants, which is also helpful for the in-depth understanding of the physical and chemical mechanism of lower-layer atmosphere.This article systematically summarized the rotorcraft UAV-based ABL observational experiments and their advantages.The impact of rotorcraft UAV on meteorological and environmental observation and its suitable boarding scheme were illustrated by placing sensors at different positions of self-developed ABL UAV observation platform and conducting comparative observation experiments among rotorcraft UAV, air sounding balloons, and high observation tower.The experiment of vertical observation in ABL from 0-1000 m under a heavy pollution condition was carried out in Hubei province and suitable correction schemes for vertical observation of meteorological elements and pollutants in ABL combing with UAV's attitude data were also developed.The results show that a set of high-quality atmospheric profile data with a vertical resolution of 2 m to 10 m is acquired based on the above-mentioned experiments, which can finely capture the vertical change characteristics of some elements such as the heights of ABL and its temperature inversion layer as well as pollutants concentration.This research aims to provide an available observation method with feasible technical solutions and robust data for the scientific application of observation using rotorcraft UAV.
