Modeling radio emission attenuation lanes observed by the Galileo and Cassini spacecraft
Gurnett, D. A.; Hospodarsky, G. B.; Kurth, W. S. +3 more
The Cassini gravity-assisted flyby of Jupiter provided an opportunity to investigate radio emission attenuation lanes that were previously observed in the Voyager and Galileo data. The Cassini radio and plasma wave science (RPWS) investigation is the most advanced plasma wave instrument to visit the Jovian system, measuring electric fields over th…
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 …
Identification of low frequency waves in the vicinity of the terrestrial bow shock
Walker, S. N.; Andre, M.; Balikhin, M. A. +1 more
In this paper, methods for the determination of the wave mode for low frequency waves based on observed differences in phase are reviewed. Examples, using measurements made in the terrestrial foreshock and magnetosheath, are used to illustrate the application of these methods. The use of advance methods such as NARMAX modelling or genetic algorith…
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…
