Methane Abundance on Titan, Measured by the SpaceTelescope Imaging Spectrograph
Although methane is the dominant absorber in Titan’s reflection spectrum, the amount of methane in the atmosphere has only been determined to an order of magnitude. We analyzed spectra from the Space Telescope Imaging Spectrograph, looking at both a bright surface region (700-km radius) and a dark surface region. The difference between the spectra of the two regions is attributed to light that ...
متن کاملValley formation and methane precipitation rates on Titan
[1] Branching valley networks near the landing site of the Huygens probe on Titan imply that fluid has eroded the surface. The fluid was most likely methane, which forms several percent of Titan’s atmosphere and can exist as a liquid at the surface. The morphology of the valley networks and the nature of Titan’s surface environment are inconsistent with a primary valley formation process involv...
متن کاملMorphology of fluvial networks on Titan: Evidence for structural control
Although Titan’s surface shows clear evidence of erosional modification, such as fluvial incision, evidence for tectonism has been less apparent. On Earth, fluvial networks with strongly preferred orientations are often associated with structural features, such as faults or joints, that influence flow or erodibility. We delineated and classified the morphologies of fluvial drainages on Titan an...
متن کاملRegional geomorphology and history of Titan’s Xanadu province
Titan’s enigmatic Xanadu province has been seen in some detail with instruments from the Cassini spacecraft. The region contains some of the most rugged, mountainous terrain on Titan, with relief over 2000 m. Xanadu contains evolved and integrated river channels, impact craters, and dry basins filled with smooth, radar-dark material, perhaps sediments from past lake beds. Arcuate and aligned mo...
متن کاملObservational evidence for cloud cover enhancement over western European forests
Forests impact regional hydrology and climate directly by regulating water and heat fluxes. Indirect effects through cloud formation and precipitation can be important in facilitating continental-scale moisture recycling but are poorly understood at regional scales. In particular, the impact of temperate forest on clouds is largely unknown. Here we provide observational evidence for a strong in...
