Abstract: AbstractOzone and temperature profiles from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) have been assimilated, using three‐dimensional variational assimilation, into a stratosphere‐troposphere version of the Met Office numerical weather‐prediction system. Analyses are made for the month of September 2002, when there was an unprecedented split in the southern hemisphere polar vortex. The analyses are validated against independent ozone observations from sondes, limb‐occultation and total column ozone satellite i...
