abstract = {Recent advances in satellite techniques hold great
potential for mapping global gravity wave (GW) processes at
various altitudes. Poor understanding of small-scale GWs has
been a major limitation to numerical climate and weather
models for making reliable forecasts. Observations of
short-scale features have important implication for
validating and improving future high-resolution numerical
models. This paper summarizes recent GW observations and
sensitivities from several satellite instruments, including
MLS, AMSU-A, AIRS, GPS, and CLAES. It is shown in an example
that mountain waves with horizontal wavelengths as short as
similar to 30 km now can be observed by AIRS, reflecting the
superior horizontal resolution in these modern satellite
instruments. Our studies show that MLS, AMSU-A and AIRS
observations reveal similar GW characteristics, with the
observed variances correlated well with background winds. As
a complementary technique, limb sounding instruments like
CRISTA, CLAES, and GPS can detect GWs with better vertical
but poorer horizontal resolutions. To resolve different
parts of the broad GW spectrum, both satellite limb and
nadir observing techniques are needed, and a better
understanding of GW complexities requires joint analyses of
these data and dedicated hieh-resolution model simulations.
