DOI: 10.1016/j.rse.2017.06.019
Abstract: Abstract The Sentinel-2A multi-spectral instrument (MSI) acquires multi-spectral reflective wavelength observations with directional effects due to surface reflectance anisotropy and changes in the solar and viewing geometry. Directional effects were examined by considering two ten… read more here.
