Abstract
Temperature, ozone and water vapour measurements from the Upper Atmosphere Research
Satellite (UARS) have been assimilated using the Met Office numerical weather prediction
data assimilation system. This paper describes the results of a three week assimilation of
Microwave Limb Sounder (MLS), ozone and temperature measurements from the late winter of
1997. Internal diagnostics of the assimilation system and independent observations have
been used to evaluate the analysed ozone fields. No inconsistencies have been found between
the MLS observations and the analysed fields. Good agreement was also found between the
assimilated fields and independent observations (HALOE and TOMS). We also intend to
assimilate GOME ozone measurements over the same period to determine what differences
occur in the final assimilated product, when using these the two different observation
datasets.
