Photodissociation Dynamics In Titan's Atmosphere
… of molecules relevant to understanding Titan's atmosphere (diacetylene, cyanoacetylene and heptane isomers) are carried out under collisionless condition using the DC slice imaging technique. In diacetylene photodissociation, two-photon processes dominate at 243 nm and 212 nm whereas at 121.6 …

Theory of the lunar photoelectron atmosphere
… An adiabatic gas model of the photoelectron atmosphere provides an independent check of the results.</p> <p>Assuming a metalic [sic] surface the electron density is of the order of 10<sup>4</sup> electrons/cm<sup>3</sup> at a half-height of the order of 1.5 cm above the lunar surface. The …

Atmosphere-vegetation interactions over South Africa
… latent heat fluxes. The results show that the atmosphere is quite sensitive to relatively small vegetation changes. Atmospheric response to vegetation perturbations indicates greater sensitivity over the NW and SE regions of southern Africa. The perturbation indicates a reduction in …

Stellar interferometry - detectors and the atmosphere.
The work in this disseration has arisen from the Cambridge Optical Aperture Synthesis Telescope (COAST) project. COAST is a novel stellar interferometer under construction in Cambridge, designed to obtain stellar images with an angular resolution equivalent to that of a 100m telescope. The success …

Acoustic Coherence Imaging Through the Atmosphere
"The imaging of acoustic ""scenes"" through the atmosphere is a subject with little treatment in the literature. This thesis strives to set the state of the art in this field by presenting imaging methods and their performance in the turbulent atmosphere. Both narrowband interferometry and wideband …

Stellar occultation investigations of Pluto's atmosphere
We investigate the shape of Pluto's atmosphere using data from the occultation of the V=15.7 star P131.1 by Pluto on 2002 Aug 21 (UT). We find that Pluto's atmosphere, as projected onto the sky, is noticeably non-circular. This implies an overall ellipsoidal shape, which could be an indication of …

Interannual middle-latitude atmosphere-ocean interactions
This thesis discusses the interaction of atmosphere and ocean in midlatitudes on interannual and decadal timescales. We investigate the extent to which mutuallycoupled atmosphere-ocean feedback can explain the observed coupled variability on these timescales, and look for preferred modes of …

Aqueous-phase Organic Chemistry in the Atmosphere
Atmospheric aqueous phases (i.e. cloud, fog and aerosol liquid water) are important reaction media for the processing of organic compounds. Quantitative data on aqueous-phase organic chemistry under the atmospheric context are sparse compared to the data from comparable gas-phase processes. A …

The carbon compounds of the primeval atmosphere
<p>The question of how and when life originated on t his planet has always been an intriguing one, exceeded perhaps in fascination only by that area of speculation which concerns itself with death and the afterlife . The latter problem has generally been approached along theological lines; the …

Surface-atmosphere coupling on Triton and Pluto.
… ambiguity in the thermal structure of Triton's atmosphere resulted from the encounter. By modeling the convective transport of heat between the surface and atmosphere I was able to show that the near-surface atmospheric temperature was close to the low end of the ra previous analyses of the …

Dynamics of planetary waves in the atmosphere
The following problems: (1) The effects of wave transience on the propagation of planetary waves in the stratosphere; (2) The coupling of the equatorial and extratropical quasi-biennial oscillations; and (3) The propagation of planetary waves between the troposphere and stratosphere; are …

Soil-Plant-Atmosphere Coupling during Interstorm Periods
… to characterize water exchange in the soil-plant-atmosphere continuum. These satellites enable evaluation of time evolution of landscape-scale plant water content during interstorm periods, providing insights into underlying mechanisms and allowing disentangling of their drivers. Here, I ask: what …
