Sensitivity Analysis and Quality Assessment of Laboratory BRDF Data

A detailed quality and sensitivity analysis of hyperspectral BRDF data, acquired under controlled laboratory conditions at the European Goniometric Facility (EGO) of the Joint Research Center, Ispra/Italy, has been performed. In regard to bidirectional reflectance measurements in the field with the FIGOS goniometer, the impact of angular data sampling, the movement of the sun, and the Lambertian assumptionof a Spectralon panel have been analyzed. An erectophile grass lawn canopy and a planophile watercress surface were chosen as main targets. A GER-3700 spectroradiometer providing hyperspectral resolutionallowed for analyzing the wavelenght-dependency of the effects.
