Estimation of surface energy from radiant surface temperature and NOAA AVHRR sensor reflectances over agricultural and native vegetation

A model is developed to evaluate surface heat flux densities using the radiant surface temperature and red and near-infrared reflectances from the NOAA Advanced Very High Resolution Radiometer sensor. When applied to relatively homogeneous agricultural and native vegetation, the model yields realist...

Description
Summary:A model is developed to evaluate surface heat flux densities using the radiant surface temperature and red and near-infrared reflectances from the NOAA Advanced Very High Resolution Radiometer sensor. When applied to relatively homogeneous agricultural and native vegetation, the model yields realistic estimates of sensible and latent heat flux density in the surface layer for cases where either the sensible or latent flux dominates.
