Airborne Observations Of Thermal Anisotropy From Urban Residential Neighbourhoods In Salt Lake City, Utah, Samantha J. Claessens
Airborne Observations Of Thermal Anisotropy From Urban Residential Neighbourhoods In Salt Lake City, Utah, Samantha J. Claessens
Electronic Thesis and Dissertation Repository
Urban surface temperatures are important variables in urban climatological processes. This thesis examines the directional variability of remotely sensed urban surface temperatures (thermal anisotropy or Λ) for three vegetated residential neighbourhoods in Salt Lake City, Utah, USA. Airborne thermal remote sensing using a thermal imager sampled the directional brightness temperature (DBT) at three times within a day for each site. Results indicate that temporal variability over a 20 – 30-minute flight was not negligible. Average DBT were then extracted from atmospherically corrected images and plotted on polar plots. For low density residential neighbourhoods Λ is increased with increasing tree-canopy coverage …
The Effect Of Sub-Facet Scale Geometry On Vertical Facet Temperatures In Urban Street Canyons, Rainer V.J. Hilland
The Effect Of Sub-Facet Scale Geometry On Vertical Facet Temperatures In Urban Street Canyons, Rainer V.J. Hilland
Electronic Thesis and Dissertation Repository
Surface temperature plays a key role in many micro-scale urban processes. Walls comprise a significant percentage of the urban surface, yet are under-represented by many methods of thermal remote sensing and not considered in detail by micro-scale surface temperature mod- els. This thesis presents a novel method of mobile thermal observation performed in urban street canyons in London, ON that uses a thermal imager as well as a visual spectrum camera to provide dense spatial and temporal resolution of micro-scale wall temperature distributions. Images are manually classified by a series of nominal variables and the resulting data set discusses the …

Perspectivas Culturais Na Comunicação Climática (Cultural Perspectives On Climate Communication), Karen E. Pennesi
Anthropology Publications
Este artigo considera que a previsão climática deve ser interpretada dentro de contextos sociais, culturais e linguísticos. Dentro de uma perspectiva antropológica baseada em entrevistas, observações e um questionário, será investigado como mudanças no meio-ambiente são entendidas por diferentes indivíduos, e transformadas em previsões que são comunicadas a diversos públicos. A linguagem utilizada e a maneira como a previsão é comunicada depende da experiência e dos objetivos do previsor, enquanto que a interpretação e a avaliação da previsão por outros são influenciadas por seus diferentes objetivos, atitudes, conhecimento e práticas. Esta etnografia da comunicação enfatiza o processo da comunicação das …
