Retrieval of aerosol optical depth over Beijing using Landsat8/OLI data

In this paper, the AOD over Beijing on Sep. 4th and Oct. 6th, 2014 are retrieved by applying DDV method using Landsat8/OLI data. Both cases show that retrieved AOD over Beijing has a higher value over urban areas and a relative lower value over mountainous area, and the distribution of AOD is greatly influenced by the land cover type. The ground-based PM2.5 data is also used to validate the derived AOD, and there is a good agreement between the AOD and PM2.5 concentrations with a high correlation coefficient of 0.8742. The calculated AOD reflects the detailed information of the atmosphere over Beijing due to its higher spatial resolution, and it is concluded that the DDV algorithm can be applied to Landsat8/OLI to retrieve AOD over Beijing.
