The phenomenon of Urban Heat Island (UHI) is a serious environmental issue affecting human health, air quality, and the living conditions of urban residents. This study uses Landsat-9 satellite imagery data to analyze the UHI phenomenon in the Hanoi area during a point in the summer of 2024. The Land Surface Temperature (LST) data from Landsat-9 were processed to determine the extent and magnitude of the urban heat island, while also investigating the relationship between factors such as building density, greenery, and land use types on the formation of UHI. The study indicated that the largest surface temperature difference between areas with abundant greenery and densely populated, built-up areas is 7.2°C, while the difference with other areas is 2.7°C. The research findings will provide deep insights into the impact of urbanization on the urban climate environment and propose solutions to mitigate the UHI effect in Hanoi.
