MIPAS measures heavy ozone in the stratosphere

The left panel shows the enrichment of ⁵⁰O₃ as a function of latitude and altitude, while in the right panel the respective standard deviations are shown. In contrast to mass spectroscopic measurements MIPAS can distinguish between the symmetric (¹⁶O ¹⁸O ¹⁶O) and the asymmetric (¹⁸O ¹⁶O ¹⁶O) heavy ozone.

Less enrichment is found for the symmetric isotopomer. Measurement noise is the largest known source of error. The total estimated retrieval error amounts are about 4% but this value does not include spectroscopic data uncertainties because no uncertainty estimates on the key spectroscopic parameters was available. The altitude resolution is around 6 km.
