Discussions have begun concerning the possibility of carrying out a new
rocket campaign
near the Sondrestrom facility in Kangerlussuaq, Greenland, to study
the complex processes at play in the high latitude E region. To kickoff
the initiative a two-hour workshop was held at the 1998 CEDAR meeting in
Boulder Colorado on June 10.
As part of its participation in the International Solar Terrestrial Physics
Program (ISTP), SRI International has scheduled, since the winter of 1995-1996,
84 intervals of Sondrestrom Incoherent scatter radar operations in coordination
with POLAR, GEOTAIL, WIND, Interball Tail, and other ISTP spacecraft. These
runs were designed to identify the mechanisms that govern reconnection
and the rate of transport in the magnetotail.
The NASA/ESA Cassini-Huygens spacecraft completed a pass by Earth toward
its encounter with Saturn in 2004.
During the Earth flyby, the Sondrestrom incoherent scatter radar measured
the high-latitude ionosphere. The radar operated between 00 UT and 15 UT
on 18 August to measure F-Region convection, Hall and Pedersen conductivity,
electron density at different altitudes, electron and ion temperature at
different altitudes, among other fundamental measurements.
January 1997 and April 1997 Solar Events
Sondrestrom Radar and Allsky Imager data associated with the January 1997
coronal mass ejection and the April 1997 solar flare and coronal mass ejection
are now online. Follow the links below :
The Ionospheric and Space Sciences staff specializes in the study of the
fundamental processes governing the nature of the upper atmosphere and
space environment. These studies involve experiments using incoherent scatter
radar, satellite and optical instruments, and radiowave diagnostics. We
perform basic physics research in the following areas:
-
Ionospheric/Magnetospheric Physics
-
Middle Atmosphere/Lower Thermosphere
-
Stratosphere/Troposphere
In addition, the staff are involved in the management and/or use of the
following research facilities:
Preprints and Recent Publications
The staff publishes in a variety of journals including the Journal
of Atmospheric and Terrestrial Physics, Radio Science, Geophysical Research
Letters, Journal of Geophysical Research, Advances in Space Research and
many others.
The following diagram illustrates some of the kinds of programs the
staff participate in:
