Piccolo, C., Dudhia, A., and Payne, V. H.: Heavy ozone enrichments from MIPAS limb emission spectra, Atmos. Chem. Phys. Discuss., 9, 25127-25158, doi:10.5194/acpd-9-25127-2009, 2009.

Vertical enrichment profiles of stratospheric heavy ozone (asymmetric and symmetric 50O3 isotopomers) have been derived from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS). As a continuously operating satellite instrument, MIPAS has an advantage over previous measurements in providing global coverage over an extended time period, allowing the variations in enrichment to be determined. However, since the spectral features of the isotopomers are comparable with the magnitude of the instrument noise, a sequential estimation retrieval scheme has been used to average the measurements zonally.
