Aerosols are crucial constituents of the atmosphere, with significant impacts on air quality. Aerosol optical depth (AOD) is critical in assessing solar resources and modeling sky radiance. However, comprehensive aerosol studies at a continental scale limited, existing methodologies need to consider spatial characteristics. This study develops spatio-temporal unmixing heterogeneity (STUH) model evaluate patterns temporal trends atmospheric aerosols across African continent. The AOD data cube, comprising monthly averaged MODIS-derived from 2001 2015, was decomposed using spatially non-negative matrix variabilization explore determinants their interactions geographically optimal zones-based (GOZH) model. Our findings reveal an increasing trend levels Africa past 15 years, combined pattern explained by five abundance variables. We find that different regions Africa, impact natural variables 1.56 3.01 times human variables, variations. These results essential for understanding climatic implications Africa.
