Remote sensing of the urban heat island effect across biomes in the continental USA
نویسندگان
چکیده
Urban heating and the formation of the urban heat island (UHI) is one attribute of urban land transformation that is of interest across science disciplines because the UHI signal reflects a broad suite of important land surface changes impacting human health, ecosystem function, local weather and possibly climate. In this paper we use a combination of satellite and ecological map data to characterize and inter-compare the UHI response across biomes in the continental US. We examine the relationship between % Impervious Surface Area and land surface temperature across many cities, calculate seasonal UHI for cities in similar ecological settings, and compare the amplitude of the UHI for the major biomes.

Remote sensing for urban heat and cool islands evaluation in semi-arid areas
Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...

Urbanization is developing unprecedentedly on a global scale. One of the chief repercussions of urbanization, caused by man-made alterations in land-use/land-cover (LULC), is the formation of urban heat islands. Albeit, differences among landscape structures and its accompanied effects on the environment are mostly neglected. Accordingly, the main objective of this study is to survey the variou...

The term urban heat island (UHI), described the phenomenon of climate change in urban areas compared with surrounding rural areas. UHI effects include: increasing in energy and water consumption, air pollution expansion and interfering in thermal comfort. Surface urban heat island (SUHI) contains patterns of land surface temperature (LST) in urban areas that has interaction with UHI in urban ca...
متن کاملData and Techniques for Studying the Urban Heat Island Effect in Johannesburg
The city of Johannesburg contains over 10 million trees and is often referred to as an urban forest. The intra-urban spatial variability of the levels of vegetation across Johannesburg’s residential regions has an influence on the urban heat island effect within the city. Residential areas with high levels of vegetation benefit from cooling due to evapo-transpirative processes and thus exhibit ...
متن کاملUrban Heat Island Analysis Using the Landsat TM Data and ASTER Data: A Case Study in Hong Kong
In this paper, the effect of urban heat island is analyzed using the Landsat TM data and ASTER data in 2005 as a case study in Hong Kong. Two algorithms were applied to retrieve the land surface temperature (LST) distribution from the Landsat TM and ASTER data. The spatial pattern of LST in the study area is retrieved to characterize their local effects on urban heat island. In addition, the co...
