The International Monitoring System (IMS), installed and maintained by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) with the support of States Signatories, is a global system of monitoring stations based on four complementary technologies: seismic, hydroacoustic, infrasound and radionuclide. One of the IMS radionuclide stations is located in Spitzbergen, the largest island of the Norwegian Svalbard Archipelago, which borders the Barents Sea and the Northern Atlantic Ocean. It has been demonstrated that signs of climate change are particularly noticeable in that region. As many other radionuclides observed in environmental measurements, Pb is always observed at IMS stations, in varying quantities. This is also the case for the IMS station RN49, Spitzbergen, where it can be demonstrated that the average concentration of the measured lead Pb increases. This is observable specifically October through December. This paper demonstrates the asset of IMS data to study climate change effects. Our conclusions are supported by global temperature anomaly data from NOAA's Global Surface Temperature Analysis, covering the period 1850 to 2023.
国际监测系统（IMS）由全面禁止核试验条约组织（CTBTO）在签署国的支持下安装和维护，是一个基于地震、水声、次声和放射性核素这四种互补技术的全球监测站系统。IMS的一个放射性核素站位于挪威斯瓦尔巴群岛最大的岛屿斯匹次卑尔根，该岛与巴伦支海和北大西洋接壤。已经证明，气候变化的迹象在该地区尤为明显。与环境测量中观察到的许多其他放射性核素一样，在IMS各监测站总能观察到不同数量的铅。位于斯匹次卑尔根的IMS站RN49也是如此，在那里可以证明所测量的铅（Pb）的平均浓度有所增加。这种情况在10月至12月尤为明显。本文展示了IMS数据在研究气候变化影响方面的价值。我们的结论得到了美国国家海洋和大气管理局（NOAA）全球地表温度分析中1850年至2023年期间全球温度异常数据的支持。
