“…The linear model indicates a highly significant, moderate influence of imperviousness on tree surface temperatures. These findings were also reported in other studies [16,56], but R 2 was considerably higher in existing work with values around 0.37 [20]. The main reason for this is the different resolution of the cited study, with ground-based thermal data and a higher-resolution imperviousness layer.…”

“…The total model only showed moderate predictive performance of surface temperatures compared to some coarser-resolution approaches of urban surface temperatures [106]. However, this model focused on tree temperatures only, and the aim of the presented approach was not to create an ideal model for tree surface temperature prediction, as this would involve many additional variables related to urban structure [16,106], but to compare the importance of tree species for surface temperature variations in parallel to other well-known predictors of surface temperatures. The importance of tree species was about the same magnitude as that of the tree NDVI, an established predictor of surface temperatures [60][61][62]103,107], showing the high relevance of tree species patterns for the urban climate.…”

“…The promotion of green vegetation, and urban trees in particular, is considered as a main strategy to alleviate this issue [6][7][8][9]. Thereby, remote sensing is crucial to quantify the cooling effects of green infrastructure [10][11][12], and several studies evaluate the impact of trees on lowering urban heat island (UHI) effects in this field [13][14][15][16][17].…”

The cooling potential of tree species in Central European cities is insufficiently studied during extreme heat and drought, although a stronger surge in heatwaves compared to the global average is observed in this region. Remote sensing-based thermal surveys are an important tool to shed light on the mitigation effects of green infrastructure, but approaches covering extreme events are scarce. In this study, we present a simple, low-cost thermal airborne methodology that covers the current daily heat record in 2022, after the second warmest and third driest spring-to-summer period since 1949, in the medium-sized German city of Forchheim. We found that in spite of record-breaking heat and drought conditions, trees still had a considerable cooling potential with surface temperatures of 2 °C to 6 °C below air temperatures. Tree species were characterized by substantial median differences in tree surface temperatures up to 3.64 °C. Conifers and drought-sensitive broadleaf species showed the highest temperatures during the extreme event, while riparian species with potentially good water provision showed the highest cooling potential. In addition to tree species, imperviousness and tree NDVI were important variables for urban tree surface temperature, showing positive (imperviousness) and negative (NDVI) correlations with tree surface temperatures. Our study provides a methodological remote sensing example for the spontaneous and rapid coverage of extreme events, documenting the benefits of tree species in the urban context.

“…Greater investment in urban infrastructure and technology can mitigate energy consumption, reduce pollution emissions, and improve the urban environment, ultimately benefitting urban residents and attracting population inflows (Fan et al, 2019). As an effective element for the adaptation to climate risks, urban greenspace plays an important role in building resilient cities by increasing surface permeability, improving air quality, and regulating microclimate (Hu et al, 2023;Jabareen, 2013;Kuang & Dou, 2020;Ma et al, 2022). However, urban greenspace exhibits uneven distribution across various scales, which could potentially impact human well-being .…”

Improving urban land use efficiency and greenness is essential for achieving sustainable urban development and improving the well‐being of urban settlements. Using satellite‐based land use data, socioeconomic data, and sustainable development goal (SDG) indicators, we quantified the changes in the urban land use efficiency and greenness under rapid urban expansion in provincial cities in the Yangtze River Economic Belt (YREB) from 1990 to 2020. Over this period, urban area increased significantly, by 254.57%, at a rate of 191.41 km2 per year in the YREB, as national macro‐policies shifted the center of urban expansion westward. Nevertheless, the urban land use efficiency and greenness have both increased. The ratio of land consumption rate to population growth rate increased from 0.55 in 1990–2000 to 0.83 in 2010–2020 in the YREB, accompanied by an increase in the investment output ratio of fixed assets. In addition, the population‐weighted greenspace exposure increased by 5.31%, due to an 8.16% increase in the urban greenspace coverage, which improved the urban living environment amidst substantial urban population growth. We emphasize the importance of fostering coordinated development between central and western cities in the YREB. The results provide an important reference for the rational allocation of land resources, improving land use efficiency, and building resilient cities within global urbanization hotspots under the SDG framework.
