Abstract

Monitoring long-term land surface temperature (LST) time series and analyzing their anomalies and trends are essential for understanding spatial patterns of global warming, particularly in Europe—the fastest-warming continent. In this study, we derived and analyzed monthly maximum LST trends over central and southern Europe at 1 km² resolution from advanced very high resolution radiometer-based TIMELINE LST data for the period 1986–2018. We found that almost 40% of the study area exhibited statistically significant (p<0.1)>0.5 K/decade and thus significantly contribute to the overall surface warming. In contrast, forested areas showed lower LST trend magnitudes (<0.5 K/decade) and a smaller share of areas with significant trends. With respect to elevation, our results revealed the lowest LST trends below 50 m and at mid-elevation ranges (750–1250 m). Both the magnitude of LST trends and the percentage area with significant trends rise towards both lower and higher altitudes. These results help to understand current warming patterns and demonstrate that long-term, high-resolution LST datasets can be used to study land-climate interactions in depth.

中欧和南欧地表温度趋势：长期（1986-2018）月最大值的推导和分析

监测长期地表温度（LST）时间序列并分析其异常和趋势对于了解全球变暖的空间格局至关重要，特别是在欧洲这个变暖最快的大陆。在这项研究中，我们从1986-2018年基于非常高分辨率辐射计的先进TIMELINE LST数据中导出并分析了中欧和南欧1 km2分辨率下的月最大LST趋势。研究发现，近40%的研究区域表现出显著的统计学意义（p0.5 K/ 10年），从而显著促进了整体地表变暖。相比之下，森林地区地表温度趋势值较小（<0.5 K/ a），趋势显著的地区所占比例较小。从高程上看，50 m以下和750 ~ 1250 m的中海拔区域地表温度变化趋势最低。地表温度变化趋势的幅度和显著趋势面积的百分比在海拔高度和海拔高度均呈上升趋势。这些结果有助于了解当前的变暖模式，并证明长期、高分辨率的地表温度数据集可用于深入研究陆地-气候相互作用。

期刊介绍： The IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing addresses the growing field of applications in Earth observations and remote sensing, and also provides a venue for the rapidly expanding special issues that are being sponsored by the IEEE Geosciences and Remote Sensing Society. The journal draws upon the experience of the highly successful “IEEE Transactions on Geoscience and Remote Sensing” and provide a complementary medium for the wide range of topics in applied earth observations. The ‘Applications’ areas encompasses the societal benefit areas of the Global Earth Observations Systems of Systems (GEOSS) program. Through deliberations over two years, ministers from 50 countries agreed to identify nine areas where Earth observation could positively impact the quality of life and health of their respective countries. Some of these are areas not traditionally addressed in the IEEE context. These include biodiversity, health and climate. Yet it is the skill sets of IEEE members, in areas such as observations, communications, computers, signal processing, standards and ocean engineering, that form the technical underpinnings of GEOSS. Thus, the Journal attracts a broad range of interests that serves both present members in new ways and expands the IEEE visibility into new areas.
