Energy Exchange Within a Corn Canopy

Abstract

<p> The results of an investigation of the micro-climate of a sweet corn canopy is reported at two stages in its development. The purpose of the experiment was to study the height dependence and diurnal variations of the net radiation, sensible and latent heat fluxes, and the turbulent transfer mechanism. Only daytime data were used.</p> <p> The depletion of net radiation in the canopy was studied within the framework of the exponential model. A new model for estimating net radiation in the canopy is developed. The pattern of the sources and sinks and the apparent turbulent transfer coefficient for sensible and latent heat in the canopy space are reported.</p>
