ABSTRACT

The presentation will showcase our recent research findings, which integrate surface data, UAV profiling, and WRF simulation to pinpoint and comprehend pollution hotspots near the foothills of central Taiwan. Sea breeze dynamics play a pivotal role in transporting coastal air pollutants inland. UAV observations provide detailed insights into the vertical structure of sea breezes and aerosol distribution. The accumulation of pollutants near the foothills results from poor ventilation and a stable nocturnal boundary layer. Terrain-induced downslope winds can exacerbate atmospheric stability and reduce boundary layer height. The presentation will delve into the severe nighttime air pollution exacerbated by these combined effects. UAV observations serve as a valuable tool in elucidating previously perplexing air pollution events.

Dr. Sheng-Hsiang (Carlo) Wang has long been dedicated to the study of atmospheric radiation and aerosols, with a focus on the optical properties of aerosols and their radiative effects. In recent years, Dr. Wang has actively participated in the 7-SEAS international research program, conducting field observation experiments in Thailand and Vietnam to gain a deeper understanding of the optical properties and vertical distribution of aerosols in the major biomass burning emission areas of northern Indochina. Additionally, he has been involved in the establishment of the Taiwan Lidar Network to study the vertical distribution characteristics of aerosols, the background atmospheric radiation monitoring stations, the development of unmanned aerial vehicle observation technology to address shortcomings in atmospheric vertical observation, and the development of miniature sensors to construct environmental Internet of Things (IoT) technology.
