Intelligent Aerial Monitoring for Air Pollution and Meteorological Variables: Spatial information about chemical composition and meteorological variables is crucial for studying the chemical/physical processes of pollutants, especially in the near-surface atmosphere, where emissions and atmospheric processes of pollutants are most vigorous. We developed an novel multicopter UAV sounding technique (MUST) serving as an integrated platform to probe a comprehensive set of atmospheric variables, including meteorological parameters (temperature, relative humidity, pressure, wind direction and speed), the chemical composition (speciated VOCs, CO, CO2, CH4, CO2 isotopologues, O3, PM2.5, and black carbon), and the radiation flux, as well as visible and thermal images. The versatile MUST has the potential to become an indispensable solution for parameters of high relevancy to the near-surface atmosphere, which could assist in atmospheric, meteorological, and interdisciplinary studies, e.g., spatial distribution and chemical/physical processes of smog and haze, pollution plume tracking, micrometeorology, determination of inversion layer heights, air-sea interactions, and investigation of industrial disasters, etc.
Environmental and Atmospheric Trace Gases: Trace gases (VOCs, CO, CO2, CH4, N2O, O3, etc.) are recognized as the principal trace constituents in the atmosphere, which play a crucial role in many important environmental issues. These issues encompass tropospheric secondary oxidant formation (e.g., organic peroxy radicals (RO2), ozone (O3), and secondary organic aerosols (SOA)), stratospheric ozone depletion, regional and global climate, and toxicity concerns. My research interests focus on the development of high performance trace gas measurement techniques to investigate the environmental problems of trace gas relevance.
