On March 1, 2002 the space-borne limb viewing mid-infrared high-resolution Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) has been brought on board the ENVISAT satellite into a polar sun-synchroneous orbit. Although the level-1 testing and validation phase has not been finished, ESA has made available datasets of 4 early orbits to several groups involved in MIPAS calibration/validation; the groups have been given the opportunity for functionality tests of their analysis codes. We here present some example results of the IMK/IAA MIPAS level-2 processor the concept of which is presented in a companion paper. Temperatures retrieved along the orbits are compared to ECMWF data. Processing parameters as chosen in pre-launch studies, such as cloud identification thresholds, microwindow selection, or instrument characteristics, are discussed. Preliminary retrievals for various atmospheric conditions are shown.
