Abstract
In the past two decades, the deterioration of air quality around the world has attracted increasing attention. Research of air pollution based on aerosol optical depth (AOD) is particularly significant. In this article, temporal and spatial changes of global aerosol optical depth from 2000 to 2019 are studied based on MODIS AOD product data, in order to reveal the change pattern of global air pollution in the past two decades. As a result of the study, the overall global AOD has been on an upward trend over the period 2000–2019. Changes in AOD during the year have obvious seasonality, in order of which is spring > summer > autumn > winter. Central Africa, South Asia and East Asia have the highest AOD, and therefore the air pollution in these areas is the most serious, however AOD in these areas is generally on the decline.
