Abstract Urban areas worldwide are experiencing escalating temperatures due to the combined effects of climate change and urbanization, leading a phenomenon known as urban overheating. Understanding spatial distribution land surface temperature (LST) its driving factors is crucial for mitigation adaptation So far, there has been an absence investigations into spatiotemporal patterns explanatory LST in city Addis Ababa. The study aims determine temperature, analyze how relationships between vary across space, compare effectiveness using ordinary least squares geographically weighted regression model these connections. findings showed that show statistically significant hot spot zones north-central parts area (Moran’s I = 0.172). relationship variables were modelled square thereby tested if dependence Koenker (BP) Statistic.The result revealed non-stationarity (p 0.000) consequently was employed performance with OLS. research that, GWR (R 2 0.57, AIC 1052.1) more effective technique than OLS 0.42, 2162.0) studying selected variables. use improved accuracy by capturing heterogeneity Statistic. ((p Consequently, Localized understanding formulated.

Developing urban agglomerations and establishing metropolitan areas have led to heat islands breaking through the original single scale form regional (RHIs) with a large influencing range in recent decades. However, spatial temporal patterns of their evolution are still poorly understood, which limit decisionmakers make more informed decisions improve environment. We selected Zhengzhou Metropolitan Area as case study MOD11A2 surface temperature products from 2001 2020 describe intensity RHIs by calculating relative temperature. Then multi-scale spatiotemporal characteristics RHI were identified help Sen + MK trend analysis, contribution index analysis standard deviation ellipse main driving factors internal relations discussed correlation Random Forest (RF) regression analysis. found that (1) increased 2970 km2 5776 2020, growth rate about 0.46% per year.

Human social positively affect RHI, vegetation strongly inhibits meteorological less influence. methods results this play significant role analyzing construction status, optimizing layouts, improving thermal environments Area.

The Urban Heat Island (UHI) phenomenon, combined with reduced vegetation and heat generated by human activities, presents a major environmental challenge for many European urban areas. UHI effect is especially concerning in hot temperate climates, like the Mediterranean region, during summer months as it intensifies discomfort raises risk of heat-related health issues. As result, assessing dynamics steering sustainable land management practices becoming increasingly crucial. Analyzing relationship between cover Land Surface Temperature (LST) can significantly contribute to achieving this objective. This study evaluates spatial correlations various types LST trends Thessaloniki, Greece, using data from Coordination Information on Environment (CORINE) program advanced index techniques within Google Earth Engine (GEE). Our analysis revealed that there has been gradual increase average surface temperature over past five years, more pronounced observed last two years (2022 2023) mean annual values reaching 26.07 °C 27.09 °C, respectively. By employing indices such Normalized Difference Vegetation Index (NDVI) performing correlation analysis, we further analyzed influence diverse landscapes distribution across different use categories area, contributing deeper understanding effects.
