“…Previous reviews of SUHI research have concentrated mostly on summarizing the methods, applications, and limitations of thermal remote sensing techniques based on representative literature [28,29,[34][35][36] and/or a more general topic that only partially covered SUHI [7,8,24,37]. For example, Gallo et al [34] reviewed several satellite-based SUHI studies between 1972 and 1993 and emphasized the application of Normalized Difference Vegetation Index (NDVI) data in SUHI research.…”

The surface urban heat island (SUHI), which represents the difference of land surface temperature (LST) in urban relativity to neighboring non-urban surfaces, is usually measured using satellite LST data. Over the last few decades, advancements of remote sensing along with spatial science have considerably increased the number and quality of SUHI studies that form the major body of the urban heat island (UHI) literature. This paper provides a systematic review of satellite-based SUHI studies, from their origin in 1972 to the present. We find an exponentially increasing trend of SUHI research since 2005, with clear preferences for geographic areas, time of day, seasons, research foci, and platforms/sensors. The most frequently studied region and time period of research are China and summer daytime, respectively. Nearly two-thirds of the studies focus on the SUHI/LST variability at a local scale. The Landsat Thematic Mapper (TM)/Enhanced Thematic Mapper (ETM+)/Thermal Infrared Sensor (TIRS) and Terra/Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) are the two most commonly-used satellite sensors and account for about 78% of the total publications. We systematically reviewed the main satellite/sensors, methods, key findings, and challenges of the SUHI research. Previous studies confirm that the large spatial (local to global scales) and temporal (diurnal, seasonal, and inter-annual) variations of SUHI are contributed by a variety of factors such as impervious surface area, vegetation cover, landscape structure, albedo, and climate. However, applications of SUHI research are largely impeded by a series of data and methodological limitations. Lastly, we propose key potential directions and opportunities for future efforts. Besides improving the quality and quantity of LST data, more attention should be focused on understudied regions/cities, methods to examine SUHI intensity, inter-annual variability and long-term trends of SUHI, scaling issues of SUHI, the relationship between surface and subsurface UHIs, and the integration of remote sensing with field observations and numeric modeling.

“…In addition, rising temperatures due to global climate change is amplified by the effect of urban heat islands [4]. This phenomenon is widely analyzed and is one of the major themes of urban climatology, particularly its impact on human health [5]. An Urban Heat Island (UHI) is characterized by a difference in temperature between an urban area and the surrounding rural environments.…”

Evaluation of the Effect of Urban Redevelopment on Surface Urban Heat Islands

Climate change is a global challenge with multiple consequences. One of its impacts is the increase in heatwave frequency and intensity. The risk is higher for populations living in urban areas, where the highest temperatures are generally identified, due to the urban heat island effect. This phenomenon has recently been taken into account by local elected officials. As a result, developers have decided to use solutions in redevelopment projects to combat high temperatures in urban areas. Consequently, the objective is to study the land-surface temperature evolution of six main urban redevelopments in Lyon, France, from 2000 to 2017. Three of them (the Confluence, Kaplan, and Museum sites) were composed of industrial areas that have undergone major transformations and are now tertiary or residential areas. Two sites have been more lightly transformed, particularly by increasing vegetation to reduce heat stress and urban flooding (Dock and Garibaldi Street). Finally, the Groupama Stadium has been built into agricultural and wooded areas. Changes in vegetation cover (NDVI), water (MNDWI), and moisture (NDMI) content, built areas (NDBI) and bare soil (NDBaI) are also monitored. The results show that the Confluence and Kaplan sites were accompanied by a decrease in surface temperature and an increase in vegetation and moisture, whereas the Groupama Stadium displayed a rise in surface temperature and a decrease in vegetation. On the other hand, the Museum, Dock, and Garibaldi sites did not exhibit clear and uniform trends, although an increase in surface temperature was shown in some statistical tests. The disparity of the results shows the necessity to include a significant amount of vegetation during redevelopment operations in order to reduce heat stress.

“…Being a concomitant impact of both urbanization and population explosion, UHI magnify the thermal contrast between urban and rural areas [3,4]. UHIs are commonly observed in densely-built areas which are associated to a larger number of buildings, compact and massive urban structures with narrow street canyons, reduced sky view factor, non-reflective and impermeable surface materials, lack of transpiring vegetation, transport flows, increased energy consumption as well as higher concentrations of urban pollutants [5,6]. The aforementioned urban complexity trap and absorb the heat from escaping into the open space, thus creating a steep temperature gradient between urban and rural areas at nights [7].…”

Background: Rapid urbanization in Kuala Lumpur Metropolitan City (KLMC) has resulted in urban heat island (UHI) effect that deteriorated public health of the urban dwellers. In a motive of identifying the heat sources, this study reported the perceived warmness and the characteristics of Open Park Spaces (OPS) that induce the reported warmness of the surrounding environment in Kuala Lumpur Metropolitan City (KLMC), a tropical city of Malaysia.Methods: A cross sectional survey using structured questionnaires is conducted on randomly clustered respondents in selected localities of KLMC from January to May, 2018. Pearson correlation is performed to examine the relationship between perceived characteristics of OPS and perceived warmness of the surrounding environment according to three time slots of a day.Results: The outcomes demonstrated that respondents felt warm during nights (89%) compared to morning (75%) and afternoon (87%). Meanwhile, the existing OPS are reported to be equipped with a mix of biodiversity such as birds, rodents and insects (89%), a mix of natural plants and animal populations (88%), water bodies (88%), variety of plants (86%), well-maintained grass surfaces (80%), ornamental flowers (79%) as well as wooded pasture (78%) in their neighbourhood. As the maximum warming sensation is reported to be felt at nights, especially in the presence of water bodies (r= 0.318, p<0.01) and wooded pasture (r= 0.222, p<0.01) in the vicinity, the integration of heat ameliorators across the existing water bodies and wood pasture deemed essential to reduce the surrounding heat impacts.Conclusion: The findings of this preliminary investigation are useful for urban designers and policy makers to make tacit evidence-based decisions.
