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 2-D 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 3-D images
of the GW temperature structures. In this paper we investigate
1) how an ILI advances measurements of GW momentum flux,
2) which additional benefits are achieved by limb imaging of GWs, and
3) 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 3-D sampling
is demonstrated. |
