Abstract

The urban heat island effect significantly challenges human health, energy consumption, and overall urban living conditions. Accurate land surface temperature (LST) measurement at fine spatial and temporal scales is essential to understand urban thermal dynamics and develop effective mitigation strategies. However, current satellite sensors offer a trade-off between spatial and temporal resolutions. This review critically examines recent techniques for enhancing the resolutions of satellite-derived LST, focusing on urban applications. A comprehensive search was conducted with Scopus and Web of Science databases using keywords related to LST resolution enhancement. After applying criteria to remove irrelevant and duplicate studies, 60 papers were selected for in-depth analysis. Our findings indicate that LST data from polar and geostationary orbit satellite thermal infrared (TIR) sensors are mainly used for resolution enhancements. The identified enhancement methods fall into three categories: spatial, temporal, and combined spatial and temporal approaches. Existing techniques achieve spatial and temporal resolutions, respectively, 10 m and 15 min. High-resolution LST data are valuable for urban planners and policymakers to assess public health risks, energy use, insurance considerations, and emergency response planning. This review provides insights into current LST resolution enhancement methods and their practical implications in addressing urban heat challenges.

提高城市环境中卫星地表温度的时空分辨率：系统的文献综述

城市热岛效应对人类健康、能源消耗和整体城市生活条件构成了重大挑战。精确的地表温度（LST）在精细时空尺度上的测量对于理解城市热动力学和制定有效的减缓策略至关重要。然而，目前的卫星传感器提供了空间和时间分辨率之间的权衡。本综述严格审查了最近用于提高卫星衍生LST分辨率的技术，重点是城市应用。在Scopus和Web of Science数据库中使用与LST分辨率增强相关的关键词进行了全面检索。在应用标准去除不相关和重复的研究后，选择了60篇论文进行深入分析。研究结果表明，极地和地球静止轨道卫星热红外（TIR）传感器的地表温度数据主要用于分辨率增强。所确定的增强方法分为三大类：空间增强、时间增强和时空结合增强。现有技术分别实现10米和15分钟的空间和时间分辨率。高分辨率LST数据对于城市规划者和决策者评估公共卫生风险、能源使用、保险考虑和应急响应规划具有重要价值。本文综述了当前地表温度分辨率增强方法及其在解决城市热挑战中的实际意义。
