Direct stack measurements 14CO2 downwind plume measurements 14CO2 and bulk leaf 14C from Swiss cement factories

Radiocarbon data collected at multiple Swiss Cement factories, in order to estimate the fossil fraction of their emissions. Some samples were collected directly at the stack of the cement factory, and others were collected downind, in the emission plume. Bulk leaf 14C collected in the vicinity of multiple Swiss Cement factories, to estimate the fossil content of their CO2 emissions in the longer term本数据集涵盖在瑞士多家水泥厂采集的放射性碳（radiocarbon）数据，用于估算其排放物中的化石组分占比。其中部分样本直接采集自水泥厂的烟囱排气口，其余样本采集于排放羽流的下风区域。 本数据集还包含在瑞士多家水泥厂周边区域采集的批量叶片碳十四（14C）样本，用于长期估算其二氧化碳（CO₂）排放中的化石碳含量。
