Determination of the isotopic abundances of heavy O3 as observed in arctic ground-based FTIR-spectra

Meier, Arndt LU and Notholt, J (1996) In Geophysical Research Letters 23(5). p.551-554
Abstract
Ground-based FTIR-measurements have been performed at the NDSC (Network for Detection of Stratospheric Change) station on Spitsbergen ((79)degrees N, 12 degrees E). We have investigated several well isolated absorption lines of isotopically heavy O-3 in the 10 mu m region that allowed us to quantify their natural abundances in the arctic atmosphere for the period April 1994 to August 1995, On the average, our solar spectra show an excess of 15.4 +/- 0.9% in (OOO)-O-16-O-16-O-18 and 11.2 +/- 1.4% in (OOO)-O-16-O-18-O-16, compared to the natural isotopic ratio in atmospheric oxygen. The lunar spectra recorded during polar night give slightly lower results. The margins of error do not include the isotopic uncertainties of the spectroscopic... (More)

The margins of error do not include the isotopic uncertainties of the spectroscopic database used (HITRAN), which might cause a shift by several percent enrichment. (Less)
