abstract = {[1] The Michelson Interferometer for Passive Atmospheric
Sounding (MIPAS) onboard the Envisat satellite provides
temperature and various gas profiles from limb-viewing
midinfrared emission measurements. The stratospheric
temperatures retrieved at the Institut fur Meteorologie und
Klimaforschung (IMK) for September/October 2002 and
October/November 2003 are compared with a number of
reference data sets, including global radiosonde (RS)
observations, radio occultation (RO) measurements of Global
Positioning System (GPS) on German Challenging Minisatellite
Payload ( CHAMP) and Argentinean Satelite de Aplicaciones
Cientificas-C (SAC-C) satellite, Halogen Occultation
Experiment (HALOE) on the Upper Atmosphere Research
Satellite (UARS), and the analyses of European Centre for
Medium-Range Weather Forecasts (ECMWF) and Met Office
(METO), United Kingdom. The data sets show a good general
agreement. Between 10 and 30 km altitude the mean
differences are within +/- 0.5 K for the averages over the
height interval and within +/-( 1 - 1.5) K at individual
levels for comparisons with RS, GPS-RO/CHAMP, and SAC-C,
ECMWF, and METO. Between 30 and 45 km the MIPAS mean
temperatures, averaged over the height region, are higher
than ECMWF but lower than METO by $\∼$ 1.5 K, while they
differ by +/- 0.5 K with respect to HALOE, with maximum
discrepancies of $\∼$ 2.5 K peaking around 35 km.
Between 45 and 50 km, MIPAS temperatures show a low bias
compared to HALOE, ECMWF, and METO with mean differences of
- 1 to - 3 K and with a better agreement with HALOE. The
large discrepancies between MIPAS and the analyses above 30
km likely suggest deficiency in the underlying general
circulation models. The standard deviations vary between 2.5
and 3.5 K for individual data sets, with more than $70\%$
being contributed from the expected variability of the
atmosphere. Retrieved temperatures with accuracy of $\∼$
0.5 - 1 K after removing the atmospheric variability provide
highly accurate knowledge to characterize our environment.},
