      abstract     = {In order to incorporate the effect of gravity waves (GWs)
                      on the atmospheric circulation most global circulation
                      models (GCMs) employ gravity wave parameterization schemes.
                      To date, GW parameterization schemes in GCMs are used
                      without experimental validation of the set of global
                      parameters assumed for the GW launch spectrum. This paper
                      focuses on the Warner and McIntyre GW parameterization
                      scheme. Ranges of parameters compatible with absolute values
                      of gravity wave momentum flux (GW-MF) derived from CRISTA-1
                      and CRISTA-2 satellite measurements are deduced for several
                      of the parameters and the limitations of both model and
                      measurements are discussed. The findings presented in this
                      paper show that the initial guess of spectral parameters
                      provided by Warner and McIntyre ( 2001) are some kind of
                      compromise with respect to agreement of absolute values and
                      agreement of the horizontal structures found in both
                      measurements and model results. Better agreement can be
                      achieved by using a vertical wavenumber launch spectrum with
                      a wider saturated spectral range and reduced spectral power
                      in the unsaturated part. However, even with this optimized
                      set of global launch parameters not all features of the
                      measurements are matched. This indicates that for further
                      improvement spatial and seasonal variations of the launch
                      parameters should be included in GW parameterization
                      schemes.},
