Core Viewpoint - The collaboration between Hefei Airport and the Chinese Academy of Sciences aims to address the challenges of air quality monitoring at airports, focusing on the emissions from aircraft during various operational phases and their environmental impact [3][4]. Group 1: Research and Development - The research team has developed three new products: an open-path ultraviolet differential absorption spectroscopy remote sensing system, an open-path Fourier transform infrared multi-component remote sensing system, and a high spatiotemporal resolution grid perception system for airport atmosphere [3]. - A comprehensive observation system has been established to monitor the emissions of pollutants, greenhouse gases, and particulate matter, achieving international advanced technical standards [3][4]. Group 2: Findings and Observations - The study revealed significant correlations between volatile organic compound emissions and aircraft types, as well as the relationship between aircraft model and CO2 emissions influenced by multiple factors such as wind speed, direction, temperature, and operational conditions [4]. - The concentration of NO2 and VOCs was found to be positively correlated with the busyness of airport runways, while pollutants dispersed quickly [4]. - The research also identified a relationship between aircraft emissions and their age, and noted that particulate matter emissions during the taxiing phase were primarily below 30nm in diameter [4]. Group 3: Future Directions - Hefei Airport plans to deepen its collaboration with the Chinese Academy of Sciences to promote the application and dissemination of research findings, contributing to the green development of the civil aviation industry and the protection of ecological environments [4].
