Web11. okt 2003 · The reflectivity is (1) where n and k are the real and imaginary components of the complex index of refraction (the optical functions) and nmed is the index of refraction of the medium ( nmed = unity for air or vacuum). The complex dielectric function ε=ε 2 + iε 1 is related to the complex optical function ( n + i k) through (2) WebTOA reflectance with a correction for the sun angle is then: ρλ = ρλ cos (θSZ) = ρλ sin (θSE) where: ρλ = TOA planetary reflectance θSE = Local sun elevation angle. The scene center sun elevation angle in degrees is provided in the metadata (SUN_ELEVATION). θSZ =Local solar zenith angle; θSZ = 90° - θSE
