Measurements of reflectance and radiant temperatures of the corn canopies were made with the Exotech 20C field spectroradiometer system and the Exotech 100 Landsat band field radiometer system at approximately 7-10 day intervals throughout the growing season. Agronomic characterization of the canopies included: leaf area index, biomass, percent soil cover, height, development stage and grain yield, vertical and oblique photographs were also taken of the canopies.
