title: A method for obtaining differential 8-13 micro spectra of the moon and other extended objects.
abstract: A method is described for measuring spectral emissivity differences in the 8-13 micro region between two points on the lunar surface which may have different temperatures. Spectral emissivity differences of 0.5% on the moon can be detected in this wavelength region, excluding the strong 9.2-10 micro atmospheric ozone band where the accuracy is reduced to 2%. The application of this method to the bright planets is discussed.
