Monitoring of land surface temperature of post-industrial areas and industrial sites in Kyiv using remote sensing data

Abstract

Within the urban heat island that exists over Kyiv, the temperature distribution strongly depends on the landscape-functional structure of the city, namely on the degree of heating and radiation of the land cover, their relationships, proportion and changes over time. Using the thermal ranges of the satellite data of the Landsat mission, we have considered why, and where exactly, the land surface temperature changes (LST) occur from 1986 to 2018. The spatio-temporal analysis of LST is performed using profiles that cross industrial and post-industrial territories of Kyiv. It’s been shown that such territories have higher level of land surface temperature according to artificial covering surface density increasing. The Shulyavsk and Svyatoshinsk industrial zones that historically exists in central and west part of the city have been taken, as example. The post-industrial transformation of such, territories today unfortunately, does not meet the requirements of the revitalization in spite of their transformation and a decreasing in the production load. The most intense temperature increases are recorded on the outskirts of the city through new housing construction and destruction of natural landscapes, which significantly expanded the boundaries of the urban thermal island. Analysis of the surface temperatures by seasons showed that the thermal anomalies exist over industrial areas, but the LST oscillation amplitude reaches 15оС in summer between production and forest-park areas.
