Abstract

We evaluate the contribution of the temperature-dependent emissivity to the temperature-dependent gray-body incidence detected in a wavelength interval with a thermal detector. This term, previously neglected, is shown to be significant, resulting in a 20% error for the traditional applications. The infection of vegetation with a decrease will modify its emissivity, its change of emissivity with temperature, and its temperature. The results presented here may be applied productively to monitor remotely the health of fragile crops, grown on extended areas.
