This dataset is the first-of-its-kind global long-term time series monthly 1-kilometer high-resolution spatiotemporally seamless aerosol optical depth (AOD) data product. Its temporal resolution is monthly, covering the period from 2000 to 2023. With a spatial resolution of 1 kilometer, its spatial coverage ranges from 180°W to 180°E in longitude and 58°S to 62°N in latitude. The validation accuracy of this product exceeds 0.85, providing critical data support for studies such as revealing the long-term variation patterns and spatial differentiation characteristics of global atmospheric haze pollution, estimating health risks associated with atmospheric pollution, and analyzing aerosol radiative effects.
