Recent findings from spaceborne observations of the middle atmosphere

Session ID#: 77967

Session Description:
The last decade and a half has witnessed something of a "golden age"
in spaceborne remote sounding of the middle atmosphere, with a wide
range of instruments and missions providing limb and occultation
observations of atmospheric composition, temperature, and other
parameters from the upper troposphere, through the stratosphere to the
mesosphere. Several of these instruments continue to operate well,
and new sensors are joining the fleet.

This session welcomes papers that report recent insights into middle
atmosphere phenomena and processes obtained from spaceborne
observations. Studies that employ models to further explain the
findings are welcome, as are those using satellite observations to
characterize model performance and indicate where new understanding is
needed.  Papers that motivate the need for new or
continued observations are particularly encouraged.
