Monthly mean atmospheric D14CO2 at Jungfraujoch and Schauinsland from 1986 to 2016

14CO2 observations at Jungfraujoch high altitude research station in the Swiss Alps (3450m a.s.l.) and at Schauinsland observatory (1205 m a.s.l.) in the German Black Forest are conducted to monitor the background 14CO2 level over Europe and define the reference for regional estimates of fossil fuel CO2. The record is also used for post-bomb dating of organic material (e.g. forensic studies).

针对瑞士阿尔卑斯山荣弗劳约赫高海拔研究站（海拔3450米）与德国黑森林肖因斯兰德观测站（海拔1205米）开展了碳十四二氧化碳（14CO₂）观测，以监测欧洲区域的背景碳十四二氧化碳水平，并为化石燃料二氧化碳的区域估算确立参照基准。该观测记录还可用于有机物质的核爆后年代测定（例如法医鉴定研究）。
