      abstract     = {Gravity waves are one of the main drivers of atmospheric
                      dynamics. The spatial resolution of most global atmospheric
                      models, however, is too coarse to properly resolve the small
                      scales of gravity waves, which range from tens to a few
                      thousand kilometers horizontally, and from below 1 km to
                      tens of kilometers vertically. Gravity wave source processes
                      involve even smaller scales. Therefore, general circulation
                      models (GCMs) and chemistry climate models (CCMs) usually
                      parametrize the effect of gravity waves on the global
                      circulation. These parametrizations are very simplified. For
                      this reason, comparisons with global observations of gravity
                      waves are needed for an improvement of parametrizations and
                      an alleviation of model biases.We present a gravity wave
                      climatology based on atmospheric infrared limb emissions
                      observed by satellite (GRACILE). GRACILE is a global data
                      set of gravity wave distributions observed in the
                      stratosphere and the mesosphere by the infrared limb
                      sounding satellite instruments High Resolution Dynamics Limb
                      Sounder (HIRDLS) and Sounding of the Atmosphere using
                      Broadband Emission Radiometry (SABER). Typical distributions
                      (zonal averages and global maps) of gravity wave vertical
                      wavelengths and along-track horizontal wavenumbers are
                      provided, as well as gravity wave temperature variances,
                      potential energies and absolute momentum fluxes. This global
                      data set captures the typical seasonal variations of these
                      parameters, as well as their spatial variations. The GRACILE
                      data set is suitable for scientific studies, and it can
                      serve for comparison with other instruments (ground based,
                      airborne, or other satellite instruments) and for comparison
                      with gravity wave distributions, both resolved and
                      parametrized, in GCMs and CCMs},
