Urban heat island (UHI) intensity and magnitude estimations: A systematic literature review

Science of the Total Environment, 2021
The severity of urban heat islands (UHIs) is increasing due to global and urban climate change. The damage caused by UHIs is also increasing. To establish a plan to improve the deteriorating thermal environment in cities due to UHIs and to minimize the damage, further research is needed to accurately estimate and analyze the intensity and magnitude of ...

Understanding and Analysing the Urban Heat Island (UHI) Effect in Micro-Scale

International Journal of Social Ecology and Sustainable Development, 2019
The shortage of vegetation cover alongside urban structures and land hardscape in cities causes an artificial temperature increase in urban environments known as the urban heat island (UHI) effect. The artificial heat stress in cities has a particular threat for usability and health-safety of outdoor living in public space.

Urban Changes to Control and Mitigate the Urban Heat Islands (UHI): Analysis in the Catania’s Territory

2021
Urban Heat Island (UHI) is a phenomenon whereby the centre of cities has a higher temperature than peripheral areas. If the phenomenon is not controlled there is a strong risk of worsening the quality of life of the population geographically involved.

Estimating the expansion of urban areas and urban heat islands (UHI) in Ghana: a case study

Natural Hazards, 2020
This research is focused on identifying urban sprawl pattern and extent in two rapidly growing major Ghanaian cities (Accra and Kumasi) and how urban expansion affected heat island effect over the period of 2002–2017 using remote sensing imagery. The research employed remotely sensed images from Landsat 7 and 8 missions for mapping the urban sprawl ...

Characteristics of urban heat island (UHI) source and sink areas in urban region of Shenyang

2014 Third International Workshop on Earth Observation and Remote Sensing Applications (EORSA), 2014
Based on the Landsat TM image on August 12, 2010, a 4 × 4 fishnet with 16 grids was built, and each grid was 3.5 km× 3.5 km. The changes of the LST (land surface temperature), urban heat island (UHI) source and sink areas and their corresponding percentages in the 16 grids were analyzed in order to find the optimum configuration of source and sink ...
