Abstract: The SAFIRE-A Fourier transform Far-infrared spectrometer has been involved in field campaigns carried out with the M-55 Geophysica stratospheric aircraft in 2002-2003, with the aim of contributing to the validation of level-2 products of the ENVISAT chemistry instruments. The limb sounding observations of volume mixing ratio vertical profiles of Ozone, Nitric Acid and Nitrous Oxide were especially focused on the validation of MIPAS data in the altitude range 10-20 km. Here we report the results of validation measurements performed at mid-latitude in October 2002 and in the Arctic region in March 2003. Comparison between O3, HNO3 and N2O vertical distribution measured by SAFIRE and profiles of the same species obtained by MIPAS onboard the ENVISAT satellite are presented and discussed.
