Abstract:
The surface of Titan, the largest icy moon of Saturn, is veiled by a
very thick and hazy atmosphere. The Visual and Infrared Mapping
Spectrometer onboard the Cassini spacecraft, in orbit around Saturn
since July 2004, conduct an intensive survey of Titan with the objective
to understand the complex nature of the atmosphere and surface of the
mysterious moon and the way they interact. Accurate radiative transfer
modeling is necessary to analyze Titan's infrared spectra, but are often
very computer resources demanding. As Cassini has gathered hitherto
millions of spectra of Titan and will still observe it until at least
2010, we report here on the development of a new rapid, simple and
versatile radiative transfer model specially designed to invert VIMS
datacubes.
