Abstract

Heavy oxygen isotope enrichment in stratospheric CO₂ has been identified in the past as a direct result of the large O₃ isotope anomaly though no simultaneous measurements are known. Results from 8 stratospheric balloon flights at two latitudes are reported that provide now a complete oxygen isotope analysis of both gases. An unambiguous, very tight correlation between enrichments of ¹⁷O and ¹⁸O in CO₂ has been found. The large ratio δ¹⁷O/δ¹⁸O of 1.71 ± 0.03 shows a faster transfer of ¹⁷O than of ¹⁸O into CO₂ and establishes a standard throughout the lower and middle stratosphere between midlatitudes and high northern latitudes. Ozone isotope transfer can now be treated in models with reliable atmospheric data.
