The 0.1 º aerosol optical thickness dataset (also known as the "Poles AOD Collection 1.0" aerosol optical thickness (AOD) dataset) in the polar regions from 2000 to 2020 was produced by combining Merra-2 mode data and MODIS satellite sensor AOD. The data covers the period from 2000 to 2020, with a daily time resolution, covering the "tri polar" (Antarctic, Arctic and Qinghai Tibet Plateau) region, and a spatial resolution of 0.1 degree. The verification of the measured stations shows that the relative deviation of the data is within 35%, which can effectively improve the coverage and accuracy of AOD in the polar region.

File naming and required software

yyyymmddAOD550.Antarctic. nc
yyyy represents the year, mm represents the month, dd represents the day, AOD550 represents the AOD at 550nm, and Antarctic represents the Antarctic region，NC stands for NC format storage.
Data reading mode: the data is stored in nc format and can be opened with software such as Panoply that can read nc format.
