Abstract: The space-ground integrated remote sensing and monitoring technology has become an important method for studying the source, transmission and impact of air pollution through the integration of the ground and satellite-based observation platforms. However, the ground and satellite-based remote sensing algorithms currently dominated by Europe and America are not suitable for Chinese complex atmospheric environment, and these data reliability still needs to be verified. This paper introduces the corresponding platform construction, algorithm development and application examples to further promote the autonomy of atmospheric research and clarify the development status of the space-ground integrated remote sensing and monitoring technology in China. The results show that: (1) The high-precision, real-time and continuous monitoring of air pollutant concentrations (total columns)/profiles can be achieved by establishing ground-based network with multi-site observation. The air quality monitoring network of China National Environmental Monitoring Centre (CNEMC) and the ground-based remote sensing network of the University of Science and Technology of China (USTC) have been established and operated in China. (2) The global/regional-scale air pollutant concentrations (total columns)/profiles can be obtained through the satellite payloads in the ultraviolet-visible band. The Environmental Trace Gas Monitoring Instrument (EMI) on GF-5 fills the gap in this type of satellite payloads in China. The total column retrieval algorithm based on DOAS (BOAS) and the vertical profile retrieval algorithm based on OE are the current international mainstream business algorithms. (3) The space-ground integrated remote sensing and monitoring technology is rapidly developed with the advantages of high-precision, wide-coverage and quasi-positioning, which can provide technical support for urgently needed issues such as air pollution control effectiveness assessment, mechanism research, regional transmission calculation and precise traceability. This research shows that the space-ground integrated remote sensing and monitoring technology need to be oriented towards application and business, accelerate the hardware construction of observation platform, strengthen the research and development of related retrieval algorithms, deeply integrate multi-platform data, and comprehensively promote the three-dimensional and systematic development of air pollution monitoring technology.
