Titan's atmosphere and climate
TL;DR: Titan is the only moon with a substantial atmosphere, the only other thick N2 atmosphere besides Earth's, the site of extraordinarily complex atmospheric chemistry that far surpasses any other solar system atmosphere, and the only solar system body with stable liquid currently on its surface as mentioned in this paper.
Methane drizzle on Titan
Tetsuya Tokano,Christopher P. McKay,Fritz M. Neubauer,Sushil K. Atreya,Francesca Ferri,Marcello Fulchignoni,Hasso B. Niemann +6 more
TL;DR: It is shown that the in situ data on the methane concentration and temperature profile in Titan's troposphere point to the presence of layered optically thin stratiform clouds, indicating that methane precipitation occurs wherever there is slow upward motion.
Journal ArticleDOI
Multiple origins of linear dunes on Earth and Titan
David M. Rubin,Patrick A. Hesp +1 more
TL;DR: In this article, the formation of dunes is controlled by the direction of the prevailing winds and the characteristics of the sediments, a model that could be applicable to dunes on Titan.

Global pattern of Titan's dunes: Radar survey from the Cassini prime mission
Ralph D. Lorenz,Jani Radebaugh +1 more
TL;DR: A map of the orientation and extent of Titan's sand dunes derived from the complete radar imaging dataset from the Cassini prime mission is presented in this article, where 16,000 dune segments are mapped.
Journal ArticleDOI
Linear dunes on Titan and earth: Initial remote sensing comparisons
Jani Radebaugh,Ralph D. Lorenz,Tom G. Farr,Philippe Paillou,C. J. Savage,Christopher Spencer +5 more
TL;DR: In this paper, the authors presented remote sensing images of terrestrial analogues to the dunes on Titan obtained by Landsat and radar, both at considerably higher resolution than are available at Titan, that provide information about dune landforms and processes.

An Introduction to Boundary Layer Meteorology
TL;DR: In this article, the boundary layer is defined as the boundary of a boundary layer, and the spectral gap is used to measure the spectral properties of the boundary layers of a turbulent flow.

The abundances of constituents of Titan's atmosphere from the GCMS instrument on the Huygens probe

TL;DR: Direct atmospheric measurements from the Gas Chromatograph Mass Spectrometer (GCMS), including altitude profiles of the constituents, isotopic ratios and trace species (including organic compounds), were reported, confirming the primary constituents were confirmed to be nitrogen and methane.

TL;DR: Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands.

The thermal structure of Titan's atmosphere.
TL;DR: It is concluded that the most important factors controlling Titan's thermal structure are absorption of sunlight by the stratospheric haze and the pressure-induced gas opacity in the infrared.
