Abstract:

Quasi-continuous measurement of benzene, toluene, ethylbenzene and isomers of xylene in northern England has been performed using an automated thermal desorption - gas chromatography - flame ionisation detector (TD-GC-FID) system. The TD-GC-FID system was mounted in a mobile laboratory, together with a TEOM (Tapered Element Oscillating Microbalance) system for particulate monitoring, and a weather station. Both systems have been applied to urban and suburban sites in order to examine the behaviour of BTEX aromatics at these localities, under a range of boundary layer environments. Measurement

Abstract:

Within the discipline of urban planning and design, this thesis introduces urban atmos-pheres as a theoretical concept, interlinking the urban dweller’s perception of the urban environment with the disposition of social interaction. The aim is to research how urban environments, such as main streets, are being perceived through different senses and which urban atmospheres are disposing social interaction. Framed by the literature within the discipline, the conducted case study within this thesis is revealing the multisensory perception of streets as well as a vision-dominance. Observations and

Abstract:

Volatile organic compounds (VOCs) are key precursors to ozone and particulate matter, two of the most important air pollutants. Air quality interventions have successfully reduced the release of short chain VOCs in urban areas. The increased use of diesel vehicles has created an increase in the direct emission of longer chain VOCs. However, these compounds are not considered as part of air quality strategies and there are few atmospheric measurements of them to date. This thesis details continuous measurements of VOCs in London, a developed megacity, using comprehensive two dimensional gas chr

Abstract:

In recent decades, urban natures have formed illuminating grounds for the biophysical, aesthetic, political and socio-economic transformation of postindustrial cities. In the face of the looming threats of manifold environmental crises, there is an increasing sense of urgency, within multiple realms of public and political discourse, to enhance metropolitan natures. Indeed, today’s growing importance of blue and green amenities addresses essential city services such as mobility, recreation and biodiversity. At present, the forms of urban natures are highly diversified; they include leisure spa

Sans équivalent en Europe, ce gigantesque saut d’échelle suscite non seulement un doute quant à la viabilité de cette forme urbaine nouvelle, mais il bouleverse également le type d’expériences que l’on y fait au quotidien.

Abstract:

Atmospheric mercury deposition, known to be a major source of mercury to aquatic and terrestrial environments, was studied at an urban site in Orlando, FL. Precipitation sampling was conducted from September 2003 to May 2006 at a Mercury Deposition Network site located on the University of Central Florida campus. Weekly rainfall and mercury wet deposition data were gathered from this site, which provided the framework of data for this study. Historical mercury wet deposition data from several sites in Florida were used to develop a regression model to predict mercury deposition at any location

Abstract:

In many micrometeorological studies, building resolving models usually assumea neutral atmosphere. Nevertheless, urban radiative transfers play an important role because of their influence on the energy budget. In order to take into account atmospheric radiation and the thermal effects of the buildings in simulations of atmospheric flow and pollutant dispersion in urban areas, we have developed a three-dimensional (3D) atmospheric radiative scheme, in the atmospheric module of the Computational Fluid Dynamics model Code_Saturne. The radiative scheme was previously validated with idealized case

Maps of urban mercury concentrations are used to evaluate the impact of mercury reduction interventions and estimate the distribution of health hazard. Atmospheric dispersion modeling is also used to corroborate inferences about the behaviour of urban mercury vapour that are derived from observations, and to simulate hazard distributions.

Greenhouse gas emission magnitudes, trends, and source contributions are highly uncertain, particularly at sub-national scales. As the world becomes increasingly urbanized, one potential strategy for reducing these uncertainties is to focus atmospheric greenhouse gas measurements in urban areas, where a multitude of emission processes occur, imposing a strong and persistent gradient in the local atmosphere, and contributing a significant fraction of global anthropogenic greenhouse gas emissions.

The factors involved in calculating Standard Visual Range (SVR) are discussed, and a comparison is made between the visibility reported by airport observers and the photographic slide/ optical densitometer method of calculating SVR. Using slides of Houston, Texas, from the fall and winter of 1988-89, it was found that the altitude at which the contrast measurements are made significantly affects the SVR. Also an index for predicting high and low humidity was developed using the blue/red ratio of the log exposure of the sky, and sun/shade target condition.

Abstract:

One of the remaining problems associated with the photo-degradation of organic species in the atmosphere, is concerned with the mechanisms of C<sub>5</sub> and larger fragments. In this respect the 2-pentoxy radical has been chosen as a model radical. The subsequent mechanisms for it are thought to be similar to those for all other larger species. The photolysis of 2-pentyl nitrite in the near ultraviolet (UV) region at 328-383 nm resulted in the formation of 2-pentoxy radicals and nitric oxide with the quantum yield of 0.97 ± 0.08 at 298-393K, consistent with the assumption that the quantum y

This research focusses on observing and modelling the suburban surface energy balance. The initial objective is to use measurements to elucidate the controls on the size and temporal variability of the latent heat flux. This is achieved by synchronous observations of suburban and rural energy balances. On the basis of this comparison it is proposed that the day-to-day variability of the partitioning of the suburban turbulent fluxes is linked both to larger-scale atmospheric influences and variations in the energy and moisture availability within the suburban 'canopy'.
