Using a recently published global data set of Na and Be from the global monitoring network of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO), atmospheric circulation and stratosphere-troposphere interactions are examined. Cosmogenic Na has a half-life well-suited to environmental processes with durations from several months to a decade. Combined with corresponding Be observations, these two cosmogenic isotopes form a useful environmental tracer and new radiochronometer to study physical interactions of air masses in the stratosphere and troposphere.
利用全面禁止核试验条约组织（CTBTO）全球监测网络最近公布的全球钠和铍数据集，对大气环流和平流层 - 对流层相互作用进行了研究。宇宙成因钠的半衰期非常适合于持续时间从几个月到十年的环境过程。结合相应的铍观测数据，这两种宇宙成因同位素形成了一种有用的环境示踪剂和新型放射性测年计，用于研究平流层和对流层中空气质量的物理相互作用。
