Abstract
Earth remote sensing data provide ample opportunities for monitoring the ecosystem service of surface temperature regulation. The cooling effect of green zones on the surface temperature of the city was simulated based on the initial satellite data of the Landsat 8.9 thermal survey on the example of Kyiv urbogeosystem. This made it possible to assess the corresponding ecosystem service of surface temperature regulation, which consists in the cooling effect, in 0.20–3.18°C for to the city and in 0.49–7.66°C for built-up areas. In the territories, surrounding the green zones, a great decrease in surface temperature was not obtained, with the exception for the buffer zone of 100 m.
The processed data of thermal survey also provide the study of the annual dynamics in the degree of temperature difference in built-up areas and in green zones. In absolute values, this difference is greater in the warm period of the year, in relative values it is greater in the cold period. Surface temperatures are a powerful factor in microclimate formation within the urbogeosystem. Therefore, the search of scientific-applied approaches for use of remote thermal sensing of the Earth to assess the ecosystem service of temperature regulation is perspective research.
