Radiocarbon Content of Tropospheric CO2 at China Lake, California 1977–1983

  • Rainer Berger (a1), T B Jackson (a2), Robert Michael (a2) and H E Suess (a2)

Abstract

The measurements reported here are a continuation of tropospheric radiocarbon measurements in carbon dioxide carried out since 1961 at our China Lake, California collection facility. The data show a continued decrease in radiocarbon activity from ca 330‰ in 1977 to 215‰ in 1983 in agreement with similar analyses in Europe for the same time interval.
