Abstract: In the frame of ESA ESABC (ENVISAT Stratospheric Aircraft and Balloon Campaigns) activities in 2002-2003, two Fourier transform Far-Infrared limb sounders, IBEX (Infrared Balloon Experiment) and SAFIRE-A (Spectroscopy of the Atmosphere by using Far Infrared Emission – Airborne), were deployed in mid and high latitude flights, aiming at the validation of MIPAS L2 products for O 3 and other target species. For O3, in particular, a thorough comparison was performed by using traditional correlative analyses (comparing O3 mixing ratio profiles collocated within a chosen spatial-temporal vicinity), Trajectory Hunting Technique and Quasi-Conservative Coordinate analyses. We report details of the data comparisons and show how complementary information derived from different validation techniques and tools can contribute to the quality assessment of MIPAS O3 data retrieved from observations during the instrument full spectral resolution mission (July 2002 – March 2004).
