| Summary: | 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.
