MIPAS-STR data analysis of APE-GAIA measurements

Airborne measurements by MIPAS-STR (Michelson Interferometer for Passive Atmospheric SoundingSTRatospheric aircraft) during the APE-GAIA (Airborne Polar Experiment Geophysica Aircraft In Antarctica) campaign were analysed. For phase correction of the interferograms and radiometric calibration specific schemes were applied to correct for beam splitter emission and atmospheric signatures in the deep space spectra. Characteristic features of the instrumental performance and auxiliary data needed for the retrieval are described. The retrieval of temperature along the flight track is shown for one selected day. These data are compared with independent insitu measurements and global temperature analysis fields.
