      abstract     = {Atmospheric gravity waves are a major cause of uncertainty
                      in global atmospheric models. This uncertainty affects
                      regional climate projections and seasonal weather
                      predictions. Improving the representation of gravity waves
                      in global atmospheric models, is therefore of primary
                      interest. In this regard, measurements providing an accurate
                      3-D characterization of gravity waves are needed. Using the
                      Gimballed Limb Observer for Radiance Imaging of the
                      Atmosphere (GLORIA), the first airborne implementation of a
                      novel infrared limb imaging technique, a gravity wave event
                      over Iceland was measured. An air volume disturbed by this
                      gravity wave, was investigated from different angles by
                      encircling the volume with a closed flight pattern. Using a
                      tomographic retrieval approach the measurements of this air
                      mass under different angles allowed for a 3-D reconstruction
                      of the temperature and trace gas structure. The temperature
                      measurements were used to derive gravity wave amplitudes,
                      3-D wave vectors, and direction-resolved momentum fluxes.
                      These parameters facilitated the backtracing of the waves to
                      their sources on the south coast of Iceland. Two wave
                      packets are distinguished, one stemming from the main
                      mountain ridge in the South of Iceland, a second one from
                      the smaller mountains in the North. The total,
                      area-integrated fluxes of these two wave packets are
                      determined. Following the waves forward with a ray-tracing
                      model highlighted the importance of 3-D propagation, an
                      effect generally neglected in global atmospheric models.},
