An algorithm for retrieving aerosol optical depth from Landsat 8 Operational Land Imager in Vietnam

open access: yesGeocarto International, 2023
High-resolution aerosol products offer advantages over lower spatial-resolution products for monitoring pollution in urban areas and industrial zones. Therefore, in this study we develop a Landsat 8 algorithm to retrieve aerosol optical depth (AOD) based
