Observations of Mars, Uranus, Neptune, Io, Europa, Ganymede, and Callisto at a wavelength of 2.66 mmAn accurate thermal model of Mars is presently used as a calibrator for 2.66-mm brightness temperature observations of Uranus, Neptune, and the Galilean satellites. While the measurements for Io, Europa, and Callisto, are consistent with thermal models of the lunar type, Ganymede is found to be anomalous. It appears that the near surface of Ganymede differs from that of the other satellites in some unknown fashion, perhaps by scattering more strongly at short wavelengths.
