| Zusammenfassung |
| Gravity wave (GW) remote sensing from space now has reached a stage of maturity that some
first confinements for GW modeling can be deduced. This is in particular due to global
distributions of absolute values of GW momentum flux from infrared limb sounders and due
to 2D maps of the horizontal wave field provided by nadir viewing instruments. The logical
step forward is an infrared limb imager (ILI) which combines the good vertical resolution of
limb sounding with horizontal mapping capabilities and provides 3D images of the GW
temperature structures. We investigate
how an ILI advances measurements of GW momentum flux,
which additional benefits are achieved by limb imaging of GWs, and
how an ILI compares to other GW momentum flux measurements, in-situ,
ground-based, and from space.
In particular, the large advance made by gaining regular 3D sampling is demonstrated. |
