JSM07 Application of GPS Techniques in the Atmosphere (IAMAS [ICMA], 
IAGA, IAG) 

Signals from GNSS (Global Navigation Satellite Systems) such as GPS and
GLONASS received on the ground can effectively be used for monitoring
the behavior of water vapor in the lower atmosphere. From GPS
propagation delay in a moist atmosphere, the amount of precipitable
water vapor is accurately estimated. Applying tomographic techniques
three-dimensional distributions of water vapor can be derived from data
of a dense GPS receiver network. GPS signals received on Low Earth
Orbiting (LEO) satellites are used for an active limb-sounding of the
atmosphere. Recent LEO missions such as GPS/MET, Oersted, CHAMP, SAC-C
have achieved significant progress in measuring water vapor and
temperature profiles in the troposphere and stratosphere. The GPS
occultation technique is also applicable to the planetary boundary layer
by using GPS receivers on top of high mountains, on balloons and aboard
aircrafts. The GPS remote sensing has become a powerful tool for
scientific research, and provided valuable data-sets for assimilation
into climate and numerical weather prediction models. This symposium
shall be a forum for discussing recent developments in retrieval
techniques, new findings and applications in atmospheric research, as
well as technical questions/solutions for operational monitoring of the
atmosphere by ground, air and space based GNSS receivers.

GAII.03 Measurement Techniques in the Middle/Upper Atmosphere and Ionosphere 
(IAGA, ICMA)

Observations of the dynamical, chemical and electromagnetic properties
of the middle/upper atmosphere and ionosphere have been significantly
improved in the last decades owing to development of new instruments and
essential advance in retrieval and computer technique. The purpose of
this symposium is to provide a forum for discussing recent
accomplishments in remote-sensing measurements from ground and space. We
welcome papers dealing with ground-based radio and optical techniques of
the middle atmosphere, lower thermosphere and ionosphere, such as
incoherent scatter, MST, MF and meteor radars, Rayleigh and resonance
validation and comparison of new satellite instruments in flight and
planned. In particular, we highlight recent development in GNSS (Global
Navigation Satellite Systems) sounding of the ionosphere, e.g.,
ionospheric TEC mapping with a dense GPS receiver network,
imaging/profiling of spatial/temporal structures of the E, F-region, and
topside ionosphere by ground and space based GNSS receivers.
