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.

This study investigates the impact of green spaces on enhancing thermal microclimate Biskra University campus, located in a hot and arid urban environment southeastern Algeria. Through an experimental approach, air temperature, relative humidity, airspeed were measured at five distinct points, each representing varying vegetation characteristics. The results reveal that significantly reduces ambient temperatures, with differences up to 2.6°C observed between measurement sites. Key findings indicate cooling efficiency is influenced by several factors, including type density vegetation, time day, exposure solar radiation, nature surrounding surfaces. Among types, trees demonstrated greater effectiveness than grass, particularly when densely planted. concludes strategic placement, combined additional shading structures such as pergolas well-planned spatial orientation, can improve microclimatic conditions environments. These underscore potential integrating into planning mitigate heat enhance comfort challenging climates.
