Global observations of stratospheric heavy ozone isotopologue enrichment with the Odin Sub-Millimetre Radiometer
Conference contribution, 2013

The Odin Sub-Millimetre Radiometer (SMR) measures thermal emission lines of several minor ozone isotopologues such as symmetric and asymmetric O3-18 and asymmetric O3-17 at the atmospheric limb. The global data set spans over 11 years starting in late 2001. The basic characteristics and limitations of the observational data are presented and the global distribution of heavy ozone isotopologue enrichment as seen by Odin is described and discussed. Best results in terms of spatial coverage are obtained for asymmetric O3-18, which shows a characteristic increase of the enrichment in the middle to upper stratosphere and the smallest enrichment in the polar lower stratosphere. Symmetric O3-18 is characterised by a layer of maximum enrichment in the middle stratosphere.
