Urban meteorological networks (UMNs) have thus emerged in recent decades to collect data for urban climate research worldwide. Government involvement in an UMN project is beneficial to standardizing network configurations, maintaining stations durability, striking a balance between stakeholders from various disciplines, and the implementation of future climate-related policies. This review draws upon a total of 33 government-involved projects, examining their project objectives and outcomes, UMN configurations, and management methods. There are two common network types: single-sourced UMNs which are deployed more systematically, and crowdsourced UMNs which can be managed in a more cost-efficient manner while promoting citizen science. A major advantage of UMNs over conventional regional meteorological networks is its high-density setting that can increase spatial resolution of weather observations within the city. However, most UMNs are still at an experimental stage, and have room for improvement in data quality and robustness. Nevertheless, the reviewed projects demonstrated their importance in improving the understanding of urban microclimates, weather services, and cross-disciplinary research. To facilitate further advancement in the field of urban climate research, more comprehensive yet locally-adaptable guidelines are recommended regarding UMN setup, management, data quality check and interpretation. Governments are encouraged to continue taking the lead in collaborating with local communities and other cities, so that the full potential of UMNs in enhancing urban living quality and formulating future climate-related policies can be unleashed.</div></div>","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"61 ","pages":"Article 102409"},"PeriodicalIF":6.0,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, the morphological spatial pattern analysis (MSPA) theory was used to identify the heat sources and evaluate their significance. Second, the cool network was created by identifying key nodes and corridors using circuit theory. To reduce the urban heat island effect (UHI), the cool network was finally optimized using node and corridor reduction, and its overall connectivity was assessed using α, β, and γ. The results indicate that the number of heat sources in the CPUA increased from 10 to 23 between 2000 and 2020.

From 2000 to 2020, the overall connectivity of the cool network of the CPUA increased, and the efficiency of heat transfer between the source sites of the thermal environment rose. The number of cold corridors after optimization (2020) is nearly cut in half, the overall connectivity of the cool network is decreased, and the transfer efficiency of heat between network sources is reduced.

While international network memberships influence LCCAP targets, a gap remains in addressing vulnerable groups. Additionally, 11 of the 18 SECAPs were funded by municipal resources, showing strong local commitment.

Understanding the driving factors of urban thermal environments is crucial for environmental protection. Current research focuses more on natural factors like vegetation and land cover rather than social factors such as population activity and building function. Recent studies have started to quantify social factors, including building height, but the relationship between block function types and driving factors remains unclear. This paper proposes an approach to identify thermal environmental drivers in urban blocks by improving functional classification accuracy using building information. Enhanced classification improves feature homogeneity within classes and separability of driving mechanisms between classes. We developed a multidimensional driving factor analysis model and analyzed thermal environmental drivers across different block types using data from Shenyang, China. Results show our method achieves a kappa coefficient of 0.90, 0.18 higher than conventional methods. Incorporating social factors improved the regression model's R<sup>2</sup> from 0.82 to 0.84. Natural factors influence thermal environments differently based on block functions. Building geometry dominates commercial and residential zones, while land coverage dominates industrial, public service, and scenic areas. Without improved classification accuracy, identifying these dominant factors would be less precise, leading to less effective optimization strategies. Therefore, accurate functional classification is crucial for quantifying thermal environment drivers and formulating precise optimization strategies. The proposed framework, relying on open geospatial data, can be applied to other cities and provides actionable insights for mitigating urban heat islands through targeted planning.</div></div>","PeriodicalId":48626,"journal":{"name":"Urban Climate","volume":"61 ","pages":"Article 102404"},"PeriodicalIF":6.0,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
