【 摘 要 】

Land surface temperature anomalies are typical for all major cities in the world. Satellite data in the thermal infrared range are a powerful source of information for analyzing and determining of temperature anomalies. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable ecological situation in Krasnoyarsk: where, in addition to high industrial emissions, the atmospheric processes also exert their influence, which may cause the impurities linger and concentrate over the city. This paper presents a technique for monitoring the land surface temperature on the basis of thermal infrared data from the 10th band of Landsat 8 satellite. Ground-based temperature data from an environment protection state regional system for observing the state of the atmosphere in the Earth's surface layer are used. The results show that the temperature in the places of temperature anomalies is 5-8 degrees higher than the average surface temperature of the city. Based on the results of an analysis of summer thermal multi-temporal space images, several thermal zones of different nature are outlined in the territory of the city.
