Using Landsat data to assess thermal conditions for urban climate adaptation plans in Poland

Summary/Abstract: The article proposes the inclusion of surface temperature (LST) distribution, derived from Landsat 8/9 satellite images, in assessing thermal conditions in urban areas. This approach is intended to assist in the development of urban climate adaptation plans. The city of Chojnice, located in northern Poland with a population of nearly 39,000 residents, has been selected as the study area to test this procedure. The proposed framework offers a more detailed diagnosis of the city's exposure, sensitivity, and vulnerability to high LSTs, particularly during late spring and summer when there is an increased risk of decreased thermal comfort for residents. The designed procedure is spatially explicit, enabling the identification of areas within the urban landscape that are most and least exposed to high temperatures. This capability allows adaptation measures to be tailored to specific locations effectively. Additionally, by utilising open data sources and allowing for adjustments to the assessment grid size, the proposed methodology can be reproduced in other cities. In Chojnice, over 60% of the city's area has a low vulnerability to heat. This is primarily found in areas with significant forest coverage, such as the northern green wedge in the Struga Jarcewska valley, near water bodies, allotment gardens, and agricultural lands. Nearly 30% of the city is classified as having high vulnerability, mainly encompassing the densely developed areas with a high density of buildings and limited green spaces. The remaining 10% of the city area, which features a diverse and mosaic land cover, falls into the medium vulnerability to heat impact category.
