Explainable machine learning to quantify the value of proximal remote sensing in latent energy flux estimation

Agricultural Water Management
Proximal remote sensing has the potential to provide critical information on vegetation biophysical factors that can predict land-atmosphere exchange of water and energy. Latent energy (LE) flux is traditionally estimated using process-based models which
