The researchers used a large aperture scintillometer to measure energy flux over a large agricultural area in north India. They found that the scintillometer accurately assessed sensible and latent heat fluxes, with positive correlations between leaf area index and latent heat flux, and negative correlations between soil moisture and sensible heat flux. The average evapotranspiration from the crop land was 1.58 mm per day, totaling 543 mm over 12 months. This study shows that scintillometry is a reliable tool for evaluating energy flux over large areas, and could be useful for crop simulation modeling and remote sensing energy balance algorithms.
