Pavements in urban area absorb more sunlight due to the canyon-like geomorphology of geometry and store heat great thermal bulk properties concrete. Heat released from pavements warms up air, contributing island. Recently, uses cool reduce pavement temperature as an island mitigation have gained momentum. Understanding solar insolation a is important adopt right option for place. This study mea...

Urban parks reduce air temperatures within and surroundings by exerting the cooling island effect, significant for mitigating urban microclimate. However, park effect may be influenced surrounding building configuration, this needs to studied in more detail, particular, explore how maximize of adjusting configuration. Thus, study, effects height, interval, orientation on a small were investigat...

The spatial and temporal differences of climate, urban heat island and future conditions were assessed for Stuttgart, a city located in complex topography in Southwest Germany. The present and future urban climate conditions were analysed using hourly measured data from 2000 to 2011 of 5 measuring stations and data from regional climate simulations. The urban heat island intensity was quantifie...

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 ...

This study investigates the diurnal, seasonal, monthly and temporal variation of land surface temperature (LST) urban heat island intensity (SUHII) over Isfahan metropolitan area, Iran, during 2003–2019 using MODIS data. It also examines driving factors SUHII like cropland, built-up areas (BI), urban–rural difference in enhanced vegetation index (ΔEVI), evapotranspiration (ΔET), white sky albed...

Green Roof (GR) is one of the most applied strategies to Mitigate Urban Heat Island (UHI) recommended for sustainable cities. This research aims examine and evaluate effect GR/UGI ratio on UHI mitigation, creating Cool (UCI). The study was carried out at Constantine, situated in East part Algeria, characterized by a semi-arid climate with high summer solar radiation intensity. An urban analysis...

Vegetation index (NDVI) was extracted from bi-temporal multispectral images based on the data obtained from Landsat ETM + on 14 th , September, 2000 , Landsat ETM + on 9 th , September, 2004 , Landsat ETM + on 15 th , May, 2008 and Landsat-8 on 21 st , May 2013 for Dangshan County in Anhui Province. Analysis and data extraction was carried out using the ENVI 5.0 software. Normalized values of t...

Urban Heat Islands (UHIs) and Cool (UCIs) can be measured by means of in situ measurements interpolation methods, which often require densely distributed networks sensors time-consuming, expensive many cases infeasible. The use satellite data to estimate Land Surface Temperature (LST) spectral indices such as the Normalized Difference Vegetation Index (NDVI) has emerged last decade a promising ...

Abstract As an alternative to mitigate the urban heat island effect, materials known as “cool surfaces” are a suitable passive technology for reducing transmittance into buildings and diminishing electricity demand cooling. However, due ageing, performance of cool surfaces becomes less effective, with decreasing solar reflectance generated by dust accumulation microbial growth. there is little ...

Urbanization is a global problem with demographic trends. The urban heat island plays a dominant role in local climate systems. Despite existing efforts to understand the impacts of multiple urbanization factors on the urban heat island globally, very little is known about the attribution of urban heat island magnitude to urbanization in different locations or developmental phases. In this stud...
