A Machine Learning Approach to Derive Aerosol Properties from All-Sky Camera Imagery

open access: yesRemote Sensing, 2023
We propose a methodology to derive the aerosol optical depth (AOD) and Angstrom exponent (AE) from calibrated images of an all-sky camera. It is based on a machine learning (ML) approach that establishes a relationship between AERONET measurements of AOD
