Separation of atmospheric and surface spectral features in Martian spectra

Dust aerosols are always present in the Martian atmosphere . They can substantially modify the spectral features of surface spectra observed from orbiting instruments. It might be then difficult to determine the relative contributions of surface emissivity and atmospheric opacity to observed spectral features.
The strong dependence of the emission (or reflectance) spectra on the roughness of the surface and the size of the dust grains seems to be a useful tool in discriminating the two components. Initial steps in this direction will be discussed.
