Urban heat islands (UHIs) increase the energy consumption of cities and impact health its residents. In light correlation between UHI variations observed at a local level within canopy layer, satellite-derived land surface temperatures (LSTs) may be insufficient to provide comprehensive information about these deleterious effects. For both LST air collected in spatially representative continuou...

Since reforms carried out in the late 1970s, China has experienced unprecedented rates of urban growth. Remote sensing data and surface observational data are used to investigate the urbanization process and related environmental consequences, focusing on extreme heat events and air pollution, in Zhejiang Province (ZJP, East China). Examination of satellite-measured nighttime light data indicat...

The impacts of climate changes on cities, which are home to over half of the world's population, are already being felt. In many cases, the intensive speed with which urban centres have been growing means that little attention has been paid to the role played by climatic factors in maintaining quality of life. Among the negative consequences of rapid city growth is the expansion of the problems...

Remote sensing data were utilized to assess urban land cover and its thermal characteristics through mapping sub-pixel impervious surfaces and assessing thermal infrared images. Landsat imagery was used to calculate variation in urban imperviousness from 1995 to 2002 in the Tampa Bay watershed, Florida. The urban-rural boundary and urban development density were defined by selecting certain imp...

Currently, strategies to mitigate urban heat island (UHI) effects and reduce building energy consumption are implemented worldwide. In Japan, as an effective means of mitigating UHI effects and saving energy of buildings, highly reflective (HR) roofs have increasingly been used. In this study, in order to evaluate the effect of HR roofs on building energy conservation, we investigated the solar...

One of the fundamental objectives of many studies on urban heat islands (UHI) involves establishing their intensity on determined nights or, if there is a sufficiently high number of observations, their maximum intensity and average intensity can also be ascertained. Regardless of the methodology employed, whether it refers to (1) differences between two fixed observatories, one urban and anoth...

Civilization and urbanization are the two key demands of humans in 20th century. Over last few decades, a considerable number human population have moved to urban areas. This phenomenon has led an explosion some major cities around globe, including Saudi Arabia. Urban Heat Island (UHI) is climatic condition which settlements experience increased air temperature than their neighboring rural coun...

This study explores the impact of street pattern measurements on urban heat islands (UHI) in arid climate Mashhad, Iran. The Landsat-8 top-of-the-atmosphere (TOA) brightness images from 2013 to 2021, average values normalized difference vegetation index (NDVI) and land surface temperature (LST) were calculated. Street measurements, including closeness-centrality, straightness, orientation, empl...

With global warming forecast to continue into the foreseeable future, heat waves are very likely to increase in both frequency and intensity. In urban regions, these future heat waves will be exacerbated by the urban heat island effect, and will have the potential to negatively influence the health and welfare of urban residents. In order to investigate the health effects of the urban heat isla...

An urban heat island (UHI) is an urban area where temperatures are higher than they are in the surrounding suburban areas. UHIs are of great scientific concern in the context of global environmental change. As a result of rapid economic development over the past three decades, the urban area in China has increased significantly. In the present study, to objectively determine the spatiotemporal ...
