【 摘 要 】

Changes in the microclimate of the urban environment often occur as a result of changes in urban development, artificial changes in the relief, and the cutting down of forest plantations. Due to changes in the urban environment there is a change in the microclimate of the city, which entails a direct change in the land surface temperature. Changes in the urban environment can be detected using space images of different spatial resolution in the visible and far infrared range. Landsat data is currently the most accessible, complete, and open for studying these changes. Thermal imaging is widely used for monitoring urban sites. To increase the spatial resolution, synthesis of Landsat-8 images with higher spatial resolution images of Planet Scope is used, which allows increasing the spatial resolution of surface temperature maps produced from Landsat-8 images from 30 meters to 3 meters. The paper presents the results of an assessment of the land surface temperature in the city of Krasnoyarsk for a two-year period from September 2016 to September 2018 based on the analysis of Landsat-8 and Planet Scope satellite images.
