Research progress on properties of aerosol concentration and particle size in atmosphere

空气质量关系人们的生活质量,气溶胶由于能直接影响空气质量,而受到越来越多的关注。通过对表征气溶胶性质的浓度和粒度两个重要特征量的研究进展进行梳理总结,以推动其在生态环境领域的基础研究和应用推广。分别从大气气溶胶浓度和粒度的数据获得方法、时空分布、影响因素等方面进行了系统的阐述分析,并对研究方向进行了展望。随着科学技术的进步,气溶胶地面监测方法将进一步优化,遥感监测将得到进一步的扩大应用,尤其从数据源和反演算法两个方面进一步提高反演的精度,而且多源大数据的应用也将是推进气溶胶研究的重要方向。

Air quality is related to people’s life quality.Aerosols are receiving more and more attention because they can directly affect air quality.The research progress of the two important characteristics of aerosol concentration and particle size was summarized,which could promote the basic research and application in the field of ecological environment.The data acquisition,spatial and temporal distribution,influencing factors of atmospheric aerosol concentration and particle size were expounded systematically,and the research prospects were also proposed.With the development of science and technology,the aerosol ground monitoring method will be further optimized,remote sensing monitoring will be further applied.In particular,the accuracy of inversion would be further improved by two aspects of data source and inversion algorithm,and the application of multi-source big data would also be an important direction to promote aerosol research.
