AB: The Michelson Interferometer for Passive Atmosphere Sounding (MIPAS) on board of ESA's ENVISAT measures the global distribution of infrared emissions by atmospheric gases from 4μm to 15μm. The upper atmosphere measurement mode spans altitudes from 20-100 km and allows for the retrieval of species from the tropopause region up to the lower thermosphere. For the modelling of the infrared radiances it is essential to include a detailed non-local thermodynamic equilibrium (non-LTE) model in the retrieval scheme. Ozone abundance is derived from the O_3(ν2) and O_3(ν3) fundamental bands at 13 μm and 10 μm. The retrieval yields global maps of day- and nighttime ozone volume mixing ratio for July 2002 and June 2003. The primary and secondary ozone maximum as well as a tertiary ozone maximum at the polar night terminator are observed. This data is compared with measurements of the HALOE and GOMOS instruments and with numerical simulations performed with the NCAR ROSE model. In the 5 μm region, the high spectral resolution of the MIPAS data allows for the separation of ozone radiance from emissions of other gases. Ozone data in this spectral region stems from highly excited vibrational states and gives information about the chemical pumping process and the collisional relaxation scheme of vibrationally excited ozone.
