Abstract:
PM2.5(Fine Particulate Matter) has become the primary air pollution pollutant in China, endangering human health. To make up for the limitations of spatial distribution of ground based monitoring sites, it has become a research hotspot by using the advantages of remote sensing satellite technology to estimate PM2.5 concentrations. The methods for estimating PM2.5 are summarized, and the advantages and disadvantages of each method are discussed, also there is a great difference in the selectivity of different application goals. It is suggested that appropriate methods should be selected for different application purpose to meet the needs of various aspects. It provides reference of PM2.5 estimation for future.
