Abstract
The process of urbanization is accelerating day by day, so this rapid development turns the natural landscape into an artificially created one [3]. In turn, the growth of urbanization causes significant changes in the natural landscape. This leads to microclimatic changes, air pollution, heat island effect etc. The UHI is an urban area whose air temperature exceeds the temperature of the suburbs by 4° or more. Due to air pollution by man-made emissions in urbanized areas, the thermal regime is changing, the concentration of carbon dioxide and water vapor has now reached 90% of the total amount of pollutants [8]. Given the potential danger of elevated values of air temperature, caused by UHI, that affect the lives of residents, the method for determining surface temperature and the location of heat islands should be determined. The purpose of this paper is to analyze the problem of urban heat islands. Using the processing and analysis of data from Google Earth Engine, to analyze changes in the number and condition of green spaces, as well as to analyze areas of interest for changes in surface temperatures over time. To identify the relationship between green spaces in megacities and the UHI. To propose an effective method of monitoring the UHI for further prevention of environmental disasters in megacities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
