      abstract     = {This paper describes a comprehensive observational filter
                      for satellite infrared limb sounding of gravity waves. The
                      filter considers instrument visibility and observation
                      geometry with a high level of accuracy. It contains four
                      main processes: visibility filter, projection of the
                      wavelength on the tangent-point track, aliasing effect, and
                      calculation of the observed vertical wavelength. The
                      observation geometries of the SABER (Sounding of the
                      Atmosphere using Broadband Emission Radiometry) and HIRDLS
                      (High Resolution Dynamics Limb Sounder) are mimicked.
                      Gravity waves (GWs) simulated by coupling a convective GW
                      source (CGWS) scheme and the gravity wave regional or global
                      ray tracer (GROGRAT) are used as an example for applying the
                      observational filter. Simulated spectra in terms of
                      horizontal and vertical wave numbers (wavelengths) of
                      gravity wave momentum flux (GWMF) are analyzed under the
                      influence of the filter. We find that the most important
                      processes, which have significant influence on the spectrum
                      are the visibility filter (for both SABER and HIRDLS
                      observation geometries) and aliasing for SABER and
                      projection on tangent-point track for HIRDLS. The vertical
                      wavelength distribution is mainly affected by the retrieval
                      as part of the "visibility filter" process. In addition, the
                      short-horizontal-scale spectrum may be projected for some
                      cases into a longer horizontal wavelength interval which
                      originally was not populated. The filter largely reduces
                      GWMF values of very short horizontal wavelength waves. The
                      implications for interpreting observed data are discussed.},
