      abstract     = {The SCanning Imaging Absorption spectroMeter for
                      Atmospheric CHartographY (SCIAMACHY) aboard the Envisat
                      satellite provided measurements from August 2002 until April
                      2012. SCIAMACHY measured the scattered or direct sunlight
                      using different observation geometries. The limb viewing
                      geometry allows the retrieval of water vapour at about 10 to
                      25 km height from the near infrared spectral range
                      (1353–1410 nm). These data cover the Upper Troposphere and
                      Lower Stratosphere (UTLS), a region in the atmosphere, which
                      is of special interest for a variety of dynamical and
                      chemical processes as well as for the radiative forcing.
                      Here, the latest data version of water vapour (V3.01) from
                      SCIAMACHY limb measurements is presented and validated by
                      comparisons with data sets from other satellite and in situ
                      measurements. Considering retrieval tests and the results of
                      these comparisons, the V3.01 data is reliable from about 11
                      to 23 km and the best results are found in the middle of the
                      profiles between about 14 and 20 km. Above 20 km in the
                      extra tropics V3.01 is drier than all other data sets.
                      Additionally, for altitudes above about 19 km the vertical
                      resolution of the retrieved profile is not sufficient to
                      resolve signals with a short vertical structure like the
                      tape recorder. Below 14 km SCIAMACHY water vapour V3.01 is
                      wetter than most collocated data sets, but the high
                      variability of water vapour in the troposphere complicates
                      the comparison. For 14 to 20 km height, the expected errors
                      from the retrieval and simulations and the mean differences
                      to collocated data sets are usually smaller than 10 $\%$
                      when the resolution of the SCIAMACHY data is taken into
                      account. In general, the temporal changes agree well with
                      collocated data sets except for the Northern Hemisphere
                      extratropical stratosphere, where larger differences are
                      observed. This indicates a possible drift in V3.01 most
                      probably caused by the incomplete treatment of volcanic
                      aerosols in the retrieval. In all other regions a good
                      temporal stability is shown. In the tropical stratosphere an
                      increase in water vapour is found between 2002 and 2012,
                      which is in agreement with other satellite data sets for
                      overlapping time periods.},
