      abstract     = {A complex gravity wave structure consisting of a
                      superposition of multiple wave packets was observed above
                      southern Scandinavia on 28 January 2016 with the Gimballed
                      Limb Observer for Radiance Imaging of the Atmosphere
                      (GLORIA). The tomographic measurement capability of GLORIA
                      enabled a detailed 3-D reconstruction of the gravity wave
                      field and the identification of multiple wave packets with
                      different horizontal and vertical scales. The larger-scale
                      gravity waves with horizontal wavelengths 5 around 400 km
                      could be characterised using a 3-D wave-decomposition
                      method. For the characterization of the smaller-scale wave
                      components with horizontal wavelengths below 200 km, the 3-D
                      wave-decomposition method needs to be further improved in
                      the future. For the larger-scale gravity wave components, a
                      combination of gravity-wave ray-tracing calculations and
                      ERA5 reanalysis fields identified orography as well as a
                      jet-exit region and a low pressure system as possible
                      sources. All gravity waves propagate 10 upward into the
                      middle stratosphere, but only the orographic waves stay
                      directly above their source. The comparison with ERA5 also
                      shows that ray-tracing provides reasonable results even for
                      such complex cases with multiple overlapping wave packets.
                      AIRS measurements in the middle stratosphere support these
                      findings, even though their coarse vertical resolution
                      barely resolves the observed wave structure in this case
                      study. The high-resolution GLORIA observations are therefore
                      an important source of information on gravity wave
                      characteristics in the upper troposphere and lower
                      stratosphere region.},
