Radiative transfer in layered media: Application to the radar sounding of Martian polar ices. II
Ilyushin, Ya. A.
The paper addresses the problem of the retrieval of the physical parameters of the Martian polar ices from the ground-penetrating radar (GPR) measurements. The results of the previous paper [Ilyushin, Y.A., Seu, R., Phillips, R.J., 2005. Subsurface radar sounding of the Martian polar cap: radiative transfer approach. Planet. Space Sci. 53(14-15), …
Titan atmosphere profiles from Huygens engineering (temperature and acceleration) sensors
Lorenz, Ralph D.
Data from several Huygens probe housekeeping sensors (an engineering accelerometer and housekeeping temperature sensors) are studied to determine how effectively such nonideal instruments may characterize the density or temperature structure of the atmosphere. While only confirming the results of the dedicated atmospheric structure instrument, thi…
The Huygens Probe Descent Trajectory Working Group: Organizational framework, goals, and implementation
Lebreton, Jean-Pierre; Witasse, Olivier; Matson, Dennis L. +3 more
Cassini/Huygens, a flagship mission to explore the rings, atmosphere, magnetic field, and moons that make up the Saturn system, is a joint endeavor of the National Aeronautics and Space Administration, the European Space Agency, and Agenzia Spaziale Italiana. Comprising two spacecraft - a Saturn orbiter built by NASA and a Titan entry/descent prob…
Statistical properties of small-amplitude Langmuir waves in the Earth's electron foreshock
Soucek, J.; Décréau, P.; Krasnoselskikh, V. V. +2 more
We present the results of a statistical study of Langmuir waves observed by the Cluster spacecraft in the Earth's electron foreshock. To classify the probability density distributions of the logarithms of the wave energies, a Pearson technique is used. We show that experimental distributions can be better approximated, in a statistical sense, by B…

Localized “Jets” of Jovian electrons observed during Ulysses’ distant Jupiter flyby in 2003 2004
Kunow, H.; Heber, B.; McKibben, R. B. +2 more
We report observations of strongly anisotropic flows of electron events originating from Jupiter that were observed during Ulysses distant Jupiter flyby. A scan of the period January 1, 2003 through February 8, 2005 (extending roughly 13 months before and after the closest approach of 0.8 AU in early 2004) identified a total of 15 events with sign…

A method to determine the atmospheric temperature profile from in situ pressure data: Application to Titan
Mäkinen, T.; Leinonen, J.; Harri, A. -M.
We have developed a new method to analyse in situ observations of atmospheric variables of state: the reconstruction of the vertical temperature profile from pressure measurements accompanied by rough knowledge of the atmospheric composition and the aerodynamical response properties of the descent vehicle. We can use the method to construct the te…

A technique to determine the mean molecular mass of a planetary atmosphere using pressure and temperature measurements made by an entry probe: Demonstration using Huygens data
Withers, P.
It is possible to determine the mean molecular mass of a planetary atmosphere using pressure and temperature measurements made by an entry probe descending at terminal velocity. The descent trajectory of an entry probe can be determined from pressure, temperature, and mean molecular mass data. This technique offers redundancy for large entry probe…
