Experimental simulation of Titan's atmosphere: Detection of ammonia and ethylene oxide

Coustenis, A.; Coll, P.; Raulin, F. +1 more

For several years now, an experimental simulation of Titan's atmosphere has been on going at LISA. A cold plasma is established in a gas mixture representative of the atmosphere of the satellite. In these experiments, more than 70 organic compounds have been identified, including the first identification in this type of experimental simulation of …

Inverse radiation modeling of Titan's atmosphere to assimilate solar aureole imager data of the Huygens probe

Keller, H. U.; Grieger, B.; Markiewicz, W. J. +1 more

During the descent of the Huygens probe through Titan's atmosphere in January 2005, the Descent Imager/Spectral Radiometer (DISR) will perform upward and downward looking measurements at various spectral ranges and spatial resolutions. This internal radiation density could be estimated by radiative transfer calculations for Titan's atmosphere. How…

Simultaneous retrieval of optical depths and scattering phase functions in Titan's atmosphere from Huygens/DISR data

Keller, H. U.; Grieger, B.; Rodin, A. V. +1 more

In January 2005, the Huygens probe will descent through Titan's atmosphere and the Descent Imager/Spectral Radiometer (DISR) will perform upward and downward looking observations at various spectral ranges and spatial resolutions. One of the subinstruments, the Upward Looking Visible Spectrometer (ULVS), measures the total downward radiation flux …

A spherical model for computing polarized radiation in Titan's atmosphere

Keller, Horst U.; Grieger, Björn; Salinas, Santo V. +1 more

The Huygens descent through Titan's atmosphere in January 2005 will provide invaluable information about Titan's atmospheric composition and aerosol properties. The Descent Imager/Spectral Radiometer (DISR) will perform upward and downward looking radiation observations at various spectral ranges and spatial resolutions. To prepare the DISR data i…
