There are many parallels between the atmospheric thermal structure of the Saturnian satellite Titan and the terrestrial greenhouse effect; these parallels provide a comparison for theories of the heat balance of Earth. Titan's atmosphere has a greenhouse effect caused primarily by pressure-induced opacity of N2, CH4, and H2. H2 is a key absorber because it is primarily responsible for the absorption in the wave number 400 to 600 cm-1 "window" region of Titan's infrared spectrum. The… 

Analytic Solutions for the Antigreenhouse Effect: Titan and the Early Earth

Abstract The antigreenhouse effect results from a high altitude haze which blocks sunlight while allowing transmission of thermal infrared. An antigreenhouse is observed on Titan and has been

The effect of atmospheric absorption of sunlight on the runaway greenhouse point

[1] The longwave emission of planetary atmospheres that contain a condensable absorbing gas in the infrared (i.e., longwave), which is in equilibrium with its liquid phase at the surface, may exhibit


Models for the origin of Titan’s atmosphere, the processing of the atmosphere and surface and its exobiological role are reviewed. Titan has gained widespread acceptance in the origin of life field

UV shielding of NH3 and O2 by organic hazes in the Archean atmosphere

The late Archean atmosphere was probably rich in biologically generated CH4 and may well have contained a hydrocarbon haze layer similar to that observed today on Saturn's moon, Titan. Here we

Coupling photochemistry with haze formation in Titan ’ s atmosphere , Part I : Model description

We introduce a new 1D coupled Radiative/Convective-Photochemical-Microphysical model for a planetary atmosphere and apply it to Titan. The model incorporates detailed radiation transfer calculations

Physical properties of the organic aerosols and clouds on Titan

Titan’s haze is optically thick in the visible, with an optical depth at 0:5 m of about three. The haze varies with latitude in a seasonal cycle and has a detached upper layer. Microphysical models,

Titan's Atmosphere and Climate

Titan is the only moon with a substantial atmosphere, the only other thick N$_{2}$ atmosphere besides Earth's, the site of extraordinarily complex atmospheric chemistry that far surpasses any other



Methane rain on Titan

Radar Reflectivity of Titan

The present understanding of the atmosphere and surface conditions on Saturn's largest moon, Titan, including the stability of methane, and an application of thermodynamics leads to a strong

Voyager 2 photopolarimeter observations of Titan

Observations of Titan's whole disk polarization at 2460 and 7500 A are presented and analyzed in terms of model scattering atmospheres. If the Titan aerosols are spherical or nearly spherical, no

Environmental Effects of an Impact-Generated Dust Cloud: Implications for the Cretaceous-Tertiary Extinctions

A model of the evolution and radiative effects of a debris cloud from a hypothesized impact event at the Cretaceous-Tertiary boundary suggests that the cloud could have reduced the amount of light at

Nuclear Winter: Global Consequences of Multple Nuclear Explosions

The potential global atmospheric and climatic consequences of nuclear war are investigated using models previously developed to study the effects of volcanic eruptions, finding long-term exposure to cold, dark, and radioactivity could pose a serious threat to human survivors and to other species.
