      abstract     = {Global gravity wave (GW) distributions are retrieved from
                      infrared emission limb soundings taken by the CRISTA
                      instrument in August 1997 and by the SABER instrument in
                      August 2003. The investigated altitudes cover the whole
                      middle atmosphere from the tropopause to the mesopause. The
                      data agree semi-quantitatively in their salient features and
                      only small deviations due to the different meteorological
                      conditions in the two years are observed. Of particular
                      interest is the decrease of GW activity at the top of the
                      southern polar vortex and an accompanying shift of GW
                      activity towards the subtropics in the mesosphere. We
                      emulate this feature by two conceptionally different models,
                      the Warner and McIntyre spectral parameterization scheme and
                      the GROGRAT GW ray tracer. Both models indicate that
                      saturation limits and GW breaking are the governing
                      processes in creating this structure. Also, both models can
                      well reproduce the global distributions except for two
                      important points: (1) convectively generated GWs in the
                      northern subtropics are largely underestimated; (2) northern
                      hemisphere high latitude activity is grossly overestimated.
                      These points indicate that GW distribution in general
                      circulation models are not fully realistic. Refined
                      measurements are required to constrain more realistic GW
                      source distributions. (C) 2006 Elsevier Ltd. All rights
