TY - JOUR TI - Assessment of thermal conditions in Krasnoyarsk urban area with use of different satellite data and geographic information system AU - Matuzko Alexandra K AU - Yakubailik Oleg E JN - Thermal Science PY - 2019 VL - 23 IS - 12 SP - 615 EP - 621 PT - Article AB - Satellite data in the thermal infrared range are a powerful source of information for the analysis and determination of city urban area temperature anomalies. The article presents a technique for monitoring the land surface temperature on the basis of combination of "Landsat 8" satellite thermal infrared data with PlanetScope satellite constellation high resolution data. Such combination of satellite data from several spacecrafts increase the detalization of temperature maps to the level of individual city blocks. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable environmental situation in Krasnoyarsk, where, in addition to high industrial emissions, their influence and atmospheric processes, leading to the fact that impurities are delayed and concentrated over the city. The results shows that the temperature in the places of thermal anomalies is 5º-8º higher than the average land surface temperature of the city. Based on the results of the analysis of summer thermal multi-temporal space images, several thermal zones of different nature were outlined on the territory under consideration. This information can be used in planning the development of the city, the design of new urban neighborhoods.
