The Multi-Angular Imaging Spectroradiometer (MISR) will image the Earth from 9 viewing angles and derive atmospheric parameters and surface reflectance. We investigate the effects of reflections within a rough terrain on reflectance retrievals with and without terrain correction. A simple wedge model is used to compute the surface radiosities as a function of solar illumination direction. For the 9 MISR view directions we compute the apparent reflectance and compare the results with a single scattering model. For a range of slopes and flat surface reflectances we compute how much the apparent reflectance changes.
