We have used spectra from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) to perform the first global retrievals of stratospheric H 2 O 2 . We demonstrate the feasibility of profile retrievals in the range 6–35 km and obtain zonal mean maps that average profiles computed from consecutive MIPAS orbits for the periods: December 2002, March, June and September 2003. The retrieved H 2 O 2 values show an equatorial mid‐stratospheric peak, enhanced values in the Antarctic springtime lower stratosphere, and diurnal/seasonal variability. Our retrieved H 2 O 2 profiles are in qualitative agreement with expected photochemistry and with a previous balloon flight.
