The urbanization effects on land surface phenology (LSP) have been investigated by many studies, but few studies focused on the temporal variations of urbanization effects on LSP. In this study, we used the MODIS EVI, MODIS LST data and China’s Land Use/Cover Datasets (CLUDs) to investigate the temporal variations of urban heat island intensity and urbanization effects on LSP in Northeast China...
This paper examines the utility of the air pollution Model (TAPM) in simulating meteorology and dispersion of PM10 and wind data in order to assess The Impacts of Wind Variability Function on Urban Heat Island for the day of 25, November, 2012 in Karaj city that experienced severe degradation in air quality. Drawing, Skew-T diagrams, maps of surface pressure (500hp), omega (850hp) and atmosp...
Urbanisation has been identified as a major threat to the environment it increases demand for urban spaces and transforms natural landscapes impervious surfaces, leading Urban Heat Island (UHI) phenomenon. Natural such vegetation water bodies act thermal sinks that absorb heat while surfaces buildings concrete pavements sources retain emit heat. The emission results in several negative effects ...
A new index of calculating the intensity of urban heat island effects (UHI) for a city using satellite skin temperature and land cover observations is recommended. UHI, the temperature difference between urban and rural regions, is traditionally identified from the 2-m surface air temperatures (i.e., the screen-level temperature T2m) measured at a pair of weather stations sited in urban and rur...
To further evaluate the factors influencing public heat and air-quality health, a characterization of how urban areas affect the thermal environment, particularly in terms of the air temperature, is necessary. To assist public health agencies in ranking urban areas in terms of heat stress and developing mitigation plans or allocating various resources, this study characterized urban heat in Cal...
As a promising application, quantitative remote sensing of urban heat island (UHI) could facilitate our understanding of urban/suburban environment and its relationship with urbanization. This paper investigates the urban heat island effect of Lanzhou, China, a densely built up city in a valley, based on Landsat ETM+ image acquired on April 22, 2000, whose spatial resolution is sufficient for m...
Urban greening has been widely regarded as the most effective, lasting, and economical strategy for alleviating effects of urban heat islands (UHIs). Previous studies on cooling effect green spaces (UGSs) tend to analyze correlation between landscape metrics land-surface temperature (LST) based a global parameter estimation, while ignoring heterogeneity autocorrelation. This study focuses sixth...
The Urban Heat Island (UHI) effect has increased with the increase in urbanisation and climate change, especially cities arid climates. This study aims to understand influence of urban forms on creating UHIs by assessing seven sites a case Mostaganem city, which is located Mediterranean coast northern Algeria. A weather station an infrared thermometer were used collect thermal data from selecte...
