Modeling Temperatures and Spectral Properties of Phobos and Deimos from CRISM and OMEGA Data

The spectral radiances of Phobos and Deimos measured by the CRISM and OMEGA instruments are composed of both reflected solar and thermally emitted contributions. Thermal emission is controlled by surface temperature, and becomes increasingly important at longer wavelengths (> 2.5μm). Here we present a method to estimate surface temperatures using pairs of spectra from locations with the same emissivity but different temperatures. Knowing the surface temperature allows us to model the reflected and emitted contributions to the total radiance, retrieve spectral reflectance, and interpret important mineralogical information.
