[Review of UAV-based Atmospheric Fine Particulate Matter and Ozone Pollution Detection and Source Localization]

In recent years, the management of atmospheric fine particulate matter(PM_2.5) pollution in China has achieved staged success, but ozone(O₃) pollution has increased rapidly. Detection and source localization of atmospheric pollutants is the basis and key to controlling the combined pollution of PM_2.5 and O₃. With the rapid development of UAV technology and sensor technology, air pollution detection based on UAV platforms can effectively obtain the structural characteristics of PM_2.5 and O₃ near the surface and accurately trace the source of air pollution events by applying the computer algorithms, with the characteristics of high timeliness, flexibility, and spatial and temporal resolution. This will help researchers understand the distribution, changes, and sources of regional pollutants and provide a scientific basis for the synergistic control of combined air pollution. This study reviewed the traditional air pollution detection methods, summarized the types of UAV platforms and detection instruments commonly used in pollution detection, concluded the applications of UAV-based PM_2.5 and O₃ pollution detection and the algorithms of pollution source localization, and discussed the future trends of UAV-based air pollution detection.
