Abstract: [1] Three techniques are described for the extraction of surface emissivity and compositional information from Thermal Emission Imaging System (THEMIS) images. Synthetic images were constructed with different atmospheric properties and random and systematic errors to estimate the uncertainty in the retrieved surface emissivity. The three techniques are as follows: (1) A constant radiance removal algorithm determines and removes a constant radiance from atmospheric emission as well as systematic calibration ra…
