Understanding how the components of cities interfere in the Urban Heat Island (UHI) has become a main great challenge for societies seeking to improve the quality of life through the implementation of urban planning criteria. In this research, the city of Granada (Spain) was divided into four local climatic zones (LCZ) according to the Corine Land Cover inventory, to study the land surface temperature (LST) and daytime and nighttime UHI using Sentinel 3 imaging. For each LCZ, urban factors were quantified by means of the Data Panel statistical analysis method, and multivariate relationships that statistically influence the UHI were determined. The results indicate an urban cooling island during the morning with a medium temperature of −0.6 K, the effect being greater in the low-density LCZ than in the high-density LCZ. At night, an UHI with an average temperature of 0.7 K is produced, this effect being greater in compact LCZs than in open ones. Two common factors significantly influence the day and night UHI: Fraction vegetation cover and solar radiation. In addition, for the day UHI, altitude and population density stand out as significant. For the night UHI, wind, impervious surface fraction factor and sky view factor additionally stand out.

对于试图通过实施城市规划标准来改善生活质量的社会来说，了解城市的组成部分如何对城市热岛（UHI）产生了巨大的挑战。在这项研究中，西班牙格拉纳达市（Granada）（西班牙）根据Corine Land Cover清单分为四个局部气候区（LCZ），以使用Sentinel 3成像技术研究地表温度（LST）以及白天和夜间的UHI。对于每个LCZ，都通过数据面板统计分析方法对城市因素进行了量化，并确定了对UHI具有统计学影响的多元关系。结果表明，早晨的城市降温岛的中温为-0.6 K，在低密度LCZ中的影响要大于在高密度LCZ中的影响。晚上，会产生平均温度为0.7 K的UHI，与紧凑型LCZ相比，这种影响更大。有两个普遍因素会严重影响白天和夜晚的UHI：部分植被覆盖和太阳辐射。此外，在UHI的这一天，海拔和人口密度也很重要。对于夜晚的UHI，风，不透水的表面比例因子和天空视野因子也更加突出。
