Abstrakt: | The localization of Surface Urban Heat Island (SUHI) as a potential heat risk for the urban population was
evaluated. The paper aimed to propose an approach to quantify and localize (SUHI) based on Landsat series
TM, ETM+, OLI satellite imageries from the period 1996-2018 and recognize the Atmospheric Urban Heat
Island (AUHI) effects from long term temperature measurements. Using the theoretical relation between the
Normalized Difference Built-up Index (NDBI), the Normalized Difference Vegetation Index (NDVI) and the
LST (Land Surface Temperature), SUHIintensity and SUHIrisk maps were created from the combination of LST,
NDVI, NDBI using threshold values to localize urban heat island in the Katowice conurbation. Negative values
of SUHI intensity characterize areas where there is no vegetation, highly built-up areas, and areas with high
surface temperatures. The urban grow – revealed from SUHI – and global climate change are acting together
to strengthen the global AUHI effect in the region as the temperature measurements were indicated. |
