Can we improve the realism of gravity wave parameterizations by imposing sources at all altitudes in the atmosphere?

A multiwave non-orographic gravity waves (GWs) scheme is adapted to represent waves of small intrinsic phase speed, inertial waves, and wave emission from all altitudes. This last change removes the launching altitude parameter, an arbitrary parameter systematically used in GW schemes. In offline ca...
