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

Estimation and counter- validation of LISS-III derived leaf area index in Deltaic vegetation [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2021
Leaf area index (LAI), a dimensionless biophysical variable is considered as one of the most important factors in characterizing canopy structure. It estimates the amount of foliage area per unit of ground area and helps indirectly to assess biomass and ...
