Description

Infrared spectra of icy satellites contain information about the surface composition and the phase state of those materials.  For example, the phase of H2O-ice can be used to interpret the temperature and radiation history of an icy surface.  Optical constants derived from laboratory data are needed to create model spectra for comparison to observations and may lead to a new understanding of surface processes.
