abstract = {The surface heat island (SHI), manifesting itself by increased surface temperatures in the city compared to the surrounding areas, is a dynamic phenomenon during the year. The study aims to recognise seasonal variability in the SHI structure (extent and composition of land cover type), and define an effective contribution and potential capability of particular land cover types for SHI development in a polycentric agglomeration based on LANDSAT satellite images. For the first time, the SHI structure was investigated separately in the urban and non-urban areas and the permanent and seasonally specific SHIs were delineated. Seasonal variability was a significant feature of SHI structure, particularly in its non-urban part, which was driven mainly by the vegetation annual cycle and altitude-dependent snow cover distribution in winter. In the majority of seasons, the intense urban SHI was conventionally compacted in the central most urbanized part of the metropolis, and its area was changing in a pulse-wise manner throughout the year from the maximum in summer to the minimum in autumn. The extent of permanent urban SHI indicating areas risky for human health was larger than the extent of seasonally specific urban SHIs. It covered 3% of GZM and was mostly composed of industrial and commercial units. Permanent non-urban SHI was scattered throughout the GZM without any clear pattern and covered only 0.4% of the entire GZM, and 75% of its area was covered by non-irrigated arable land and pastures. The identification of the surface types with permanent and seasonally variable ability to form SHI is helpful in planning urban spaces and adapting existing cities to contemporary climate changes. © 2024 The Authors},

abstract = {Progressing urbanization forces urban infrastructure development and leads to an increase in artificial impervious surfaces that directly contribute to changes in surface urban heat island (SUHI) in cities. This study discusses spatial and temporal changes in the SUHI extent and intensity in the biggest Metropoly in Southern Poland in summer between 1986 and 2021. The study is based on Landsat satellite images, demographic and land cover data from 1990 to 2018 from CORINE Land Cover (CLC) classifications. The comparison of satellite images recorded in different years, on similar dates and under similar meteorological conditions revealed an increase in the SUHI extent from 0.6 to 4.3 % between 1986 and 2021 due to increase in the share of impervious areas. Moreover, regardless of changes in spatial extent, the mean land surface temperature (LST) of all types of land cover increased, which may be related to recent warming. In the research period, permanent surface heat island covered 0.85 % of the GZM, and over 50 % of its area was located only within four cities. Although the mean LST for SUHI increased, the SUHI intensity decreased due to increased LST of the cold island. The SUHI extent was more related to the inhabitant number (correlation: 0.83 to 0.98) than population density (0.39–0.58). SUHI expansion in combination with recent warming of climate is a particularly negative effect where society is ageing, like in GZM. © 2023 The Author(s)},

abstract = {The intense development of cities and related replacement of vegetated areas with impervious surfaces contributed to the intensification of the urban heat island effect, which is a hazardous phenomenon for humans. In this study, the spatial structure of the surface heat and cold island (SHI and SCI; respectively) in the Górnośląsko-Zagłębiowska Metropolis (GZM), the most urbanized and populated area in Poland, is investigated using four Landsat 8 satellite images recorded in the summers between 2015 and 2019. The satellite images processed to the land surface temperature (LST) and the Corine Land Cover 2018 (CLC 2018) classification were used to calculate indicators of the spatial extent and intensity of SHI and SCI. Their spatial extents in the GZM ranged from 15.4 to 16.4% and 12.2–19.4%, respectively, depending on the analyzed days with a large percentage of the agricultural areas within the SHI boundaries. Therefore, an original approach to delineate the surface urban heat island (SUHI) is proposed. This approach reduced the extent of the GZM SHI by 2.9 to 2.0%, depending on the day. In the GZM, more than 70% of the SHI consisted of discontinuous urban fabric and industrial or commercial units. Heat island indices recognized the spatial structure of SUHI as an archipelago. Vegetation and crops constituted 90% of the SCI, and these land cover types explained most of the SCI variability over time compared to the SHI. The vegetation expanded, and its characteristics continually changed during the summer season. Moreover, vegetation was more sensitive to changes in meteorological conditions than impervious surfaces. The LST was most strongly correlated with the percentage share of artificial areas in the GZM districts. In turn, the correlations between LST and forest and semi natural areas were much weaker when precipitation occurred before the recording of satellite images. The intensity of SUHI in the GZM ranged from approximately 5 to 9 °C depending on the date and the method of identifying urban and nonurban areas. © 2022 The Author(s)},
