Abstract

Air pollution is one of the most critical environmental concerns affecting human health and ecosystem sustainability. This comprehensive review analyzes the evolution and current state of Remote Sensing (RS) methods for air pollution monitoring, examining over 241 relevant papers from the Scopus database using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The study systematically evaluates three main approaches: spaceborne, Manned Aerial Vehicle (MAV)-borne, and Unmanned Aerial Vehicle (UAV)-borne RS. Our analysis reveals significant technological advancements in sensors, platforms, and data processing methods. Spaceborne monitoring demonstrates enhanced spatial resolution (from 10 km to sub-kilometer) and temporal frequency (from monthly to near-real-time). MAV-based systems show superior regional mapping capabilities but face operational constraints. UAVs emerge as promising solutions for local-scale monitoring, particularly in hazardous environments, offering operational flexibility, cost-effectiveness, and the ability to capture high-resolution spatial data. The Internet of Things (IoT) has enhanced data collection networks, while integration of Artificial Intelligence (AI), specifically deep learning, has revolutionized data processing capabilities. Cloud computing platforms, particularly Google Earth Engine (GEE), have further transformed the scale and efficiency of big data analysis for air quality. The meta-analysis of COVID-19 lockdown impacts shows significant pollution reductions, with an overall average decrease of 28% across major pollutants (NO2, PM2.5, PM10, SO2, CO), though individual pollutants showed varying responses, with O3 notably demonstrating increases due to atmospheric chemistry dynamics. The review identifies current limitations and future directions, emphasizing the need for improved multi-platform and multi-sensor RS data integration, sensor miniaturization, and regulatory frameworks. This comprehensive analysis provides valuable insights for researchers, policymakers, and practitioners in environmental monitoring and public health.

空气污染观测-桥接空载与无人航空遥感:系统回顾与元分析
空气污染是影响人类健康和生态系统可持续性的最关键的环境问题之一。本综合综述分析了用于空气污染监测的遥感(RS)方法的发展和现状,使用系统评价和荟萃分析(PRISMA)指南检查了Scopus数据库中超过241篇相关论文。该研究系统地评估了三种主要方法:星载、载人飞行器(MAV)载和无人机(UAV)载RS。我们的分析揭示了传感器、平台和数据处理方法方面的重大技术进步。星载监测显示增强的空间分辨率(从10公里到亚公里)和时间频率(从每月到近实时)。基于mav的系统显示出优越的区域制图能力,但面临操作限制。无人机作为一种有前途的局部监控解决方案,特别是在危险环境中,具有操作灵活性、成本效益和捕获高分辨率空间数据的能力。物联网(IoT)增强了数据收集网络,而人工智能(AI)的集成,特别是深度学习,已经彻底改变了数据处理能力。云计算平台,特别是谷歌地球引擎(GEE),进一步改变了空气质量大数据分析的规模和效率。对COVID-19封锁影响的荟萃分析显示,污染显著减少,主要污染物(NO2、PM2.5、PM10、SO2、CO)总体平均减少28%,尽管个别污染物表现出不同的反应,其中O3由于大气化学动力学而明显增加。该综述确定了当前的局限性和未来的方向,强调需要改进多平台和多传感器RS数据集成、传感器小型化和监管框架。这一综合分析为环境监测和公共卫生领域的研究人员、政策制定者和从业人员提供了有价值的见解。

期刊介绍: Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health. It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes. International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals. Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements. This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
