The lack of a solid methodology defining urban and non-urban areas has hindered accurately estimating the Surface Urban Heat Island (SUHI). This study addresses this issue by using official national limit together with surrounding classification to define three different reference classes: adjacent (Ua), future (FUa), peri-urban (PUa), consequently providing more accurate SUHI estimation on nine northeastern Brazilian capitals. land surface temperature was obtained in Sentinel-3 satellite data for 2019 2020. Subsequently, maximum average complementary indexes, specifically Thermal Field Variation Index (UTFVI) Discomfort (TDI), were calculated. UTFVI expresses how harmful eco-environmental spaces are, very strong In addition, TDI, values between 24.6–28.8 °C, population’s thermal comfort, six capitals showing hot TDI. These findings highlight need strategies mitigate effects ensure comfort. Therefore, provides better understanding comparison region, which diverse areas, populations, demographic variations.

Global warming is precipitating an amplification of severe meteorological occurrences such as prolonged dry spells and episodes elevated temperatures. These phenomena are instigating substantial elevations in environmental warmth, with metropolitan regions bearing the brunt these impacts. Currently, extreme heat already impacting 30% global populace, forecasts suggest that this figure will escalate to 74% forthcoming years. One objectives outlined United Nations 2030 agenda, specifically within Sustainable Development Goal 11 (SDG11), attainment sustainable urban development. To achieve this, it imperative scrutinize delve into conditions order understand their dynamics comprehensively. This understanding serves foundation for implementing mitigation resilience strategies against climate change, ultimately enhancing well-being city residents. In context, field remote sensing geographic information systems has made advancements. Notably, UrbClim model, developed by European Space Agency, facilitates assessment numerous centers. research, utilizing data from UrbClim, examines evolution stress index (Hi) during Barcelona summer 2017. Leveraging Landsat 8 satellite imagery, we derived following variables: normalized difference vegetation building index. Our findings reveal conditions, Hi experiences escalation, areas characterized a higher population density industrial zones displaying lower resistance contrast rural areas, which exhibit greater Hi. disparity can be attributed coverage reduced latter areas. way, increases more quickly intensely decreases slowly when using high temperatures compared average utmost importance future planning new developments.
