note = {We are grateful to the European Space Agency (ESA) for
providing the Odin/SMR data. Odin is a Swedish led project
funded jointly by Sweden (SNSB), Canada (CSA), Finland
(TEKES), and France (CNES) and the European Space Agency
(ESA). The Improved Limb Atmospheric Spectrometer (ILAS and
ILAS-II) were were developed by the Japanese Ministry of
Environment (MOE) and were operated by the Japan Aerospace
Exploration Agency (JAXA). The ILAS/ILAS-II data was
processed at the ILAS and ILAS-II Data Handling Facility,
National Institute of Environmental Studies (NIES), Japan.
We would like to thank the UK Met Office (UKMO) and European
Center for Medium Range Weather Forecasts (ECMWF) for
providing their meteorological analyses. We also would like
to thank P. Achtert for helping with the graphic editing and
the anonymous reviewers for helpful comments. We are also
grateful to the Swedish Research Council for funding F.

abstract = {1-year data sets of monthly averaged nitrous oxide (N2O)
and ozone (O-3) derived from satellite measurements were
used as a tool for the evaluation of atmospheric
photochemical models. Two 1-year data sets, one solar
occultation data set derived from the Improved Limb
Atmospheric Spectrometer (ILAS and ILAS-II) and one limb
sounding data set derived from the Odin Sub-Millimetre
Radiometer (Odin/SMR) were employed. Here, these data sets
are used for the evaluation of two Chemical Transport Models
(CTMs), the Karlsruhe Simulation Model of the Middle
Atmosphere (KASIMA) and the Chemical Lagrangian Model of the
Stratosphere (CLaMS) as well as for one Chemistry-Climate
Model (CCM), the atmospheric chemistry general circulation
model ECHAM5/MESSy1 (E5M1) in the lower stratosphere with
focus on the Northern Hemisphere. Since the Odin/SMR
measurements cover the entire hemisphere, the evaluation is
performed for the entire hemisphere as well as for the low
latitudes, midlatitudes and high latitudes using the
Odin/SMR 1-year data set as reference. To assess the impact
of using different data sets for such an evaluation study we
repeat the evaluation for the polar lower stratosphere using
the ILAS/ILAS-II data set. Only small differences were found
using ILAS/ILAS-II instead of Odin/SMR as a reference, thus,
showing that the results are not influenced by the
particular satellite data set used for the evaluation. The
evaluation of CLaMS, KASIMA and E5M1 shows that all models
are in agreement with Odin/SMR and ILAS/ILAS-II. Differences
are generally in the range of +/- $20\%.$ Larger differences
(up to $-40\%)$ are found in all models at 500 +/- 25 K for
N2O mixing ratios greater than 200 ppbv, thus in air masses
of tropical character. Generally, the largest differences
were found for the tropics and the lowest for the polar
regions. However, an underestimation of polar winter ozone
loss was found both in KASIMA and E5M1 both in the Northern
and Southern Hemisphere.},
