摘要：

Near global ozone isotopologue distributions have been determined from infrared solar occultation measurements of the Atmospheric Chemistry Experiment (ACE) satellite mission. ACE measurements are made with a high resolution Fourier transform spectrometer. Annual and seasonal latitudinal fractionation (delta value) distributions of the ozone isotopologues (OOO)-O-16-O-16-O-18, (OOO)-O-16-O-18-O-16 and (OOO)-O-16-O-17-O-16 were obtained. Asymmetric ozone ((OOO)-O-16-O-1-O-6-O-18) shows higher fractionation compared to symmetric ozone ((OOO)-O-16-O-18-O-16). The maximum ozone fractionation occurs in the tropical stratosphere as expected from the contribution of photolysis to the enrichment of heavy isotopologues. An enhancement of the heavy ozone isotopologues is also seen in the upper stratosphere of the Antarctic polar vortex. (C) 2019 Elsevier Ltd. All rights reserved.
