Volatile organic compounds (VOCs) are key contributors to urban air pollution, playing a central role in the formation of ozone and particulate matter, both of which pose significant health risks. In cities, VOC emissions are highly variable due to complex human activities and diverse sources, leading to increased uncertainty in their chemical reactivity and emission intensity compared to other environments. In densely built urban areas, ground-based measurements often lack representativeness. Tall towers provide a more suitable platform for continuous VOC observations, offering a larger footprint and minimizing interference from surrounding structures. In our study, we conducted atmospheric measurements—including VOC concentration and flux observations—at three tall towers located in different megacities across China. This presentation will showcase our group’s recent progress in VOC measurements from tall towers in Chinese megacities.
