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...

This paper presents a simulation model, which was incorporated into a Geographic Information System (GIS), in order to calculate the maximum intensity of urban heat islands based on urban geometry data. The methodology of this study stands on a theoretical-numerical basis (Oke’s model), followed by the study and selection of existing GIS tools, the design of the calculation model, the incorpora...

The higher concentration of man-made objects like asphalt pavement and concrete structures within urban areas lead to the formation of subareas known as urban heat islands (UHI), where the ambient temperature is significantly higher. Having a good understanding of this problem is critical for better urban development. Thermal infrared (TIR, 8-12 μm) remote sensing is often used to localize UHI....

With the development of urbanization and population growth in the use of land for construction of residential and industrial areas and other infrastructure and turning to remove more vegetation,construction materials and non-systematic misuse of cities,urban areas have forced some changes that pollution and poor air quality,dehydration,high temperatures are some of its results.The temperature d...

The urban heat island (UHI) phenomenon is a harmful environmental problem in urban areas affecting both climatic and ecological processes. This paper aims to highlight and monitor the spatial distribution of Surface UHI (SUHI) in the Casablanca region, Morocco, using remote sensing data. To achieve this goal, a time series of Landsat TM/ETM+/OLI-TIRS images was acquired from 1984 to 2016 and an...

The Urban Heat Island effect concerns the higher air temperature in urban environment with respect to the rural one. This phenomenon has been well known for hundreds of years, but it has been experimentally studied only for the last few decades and in large metropolis. The paper reports on the experimental results obtained during the period 2010–2011 in a medium size city of Italy by the resear...

Rapid urbanization contributes to the development of phenomena such as climate variability, especially in tropical countries, which negatively impact ecosystems and humans, factors that influence urban sustainability. Additionally, increase building construction prevents flow wind streams contributing retention pollutants hot air masses, causing events heat islands (UHI). This study aimed analy...

Urban heat islands are characterized by high land surface temperature, low humidity, and poor vegetation, and considered to favor the transmission of the mosquito-borne dengue fever that is transmitted by the Aedes aegypti mosquito. We analyzed the recorded dengue incidence in Sao Paulo city, Brazil, in 2010-2011, in terms of multiple environmental and socioeconomic variables. Geographical info...
