CONSIDERAÇÕES SOBRE AS REFLECTÂNCIA APARENTE E DE SUPERFÍCIE

The present work discusses the incorporation of the effective angle of illumination in the apparent reflectance formula and the consequent, and necessary, dismemberment of the Irradiance in the direct and diffuse components. The correction of the atmospheric effect was performed by the DOS ("Dark Object Subtraction") model, which also allowed to quantify the diffuse irradiance in each spectral band and to describe the hemispherical-conical reflectance with better modeling.
