Rockets at Sondrestrom

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.

Convection and Reconnection in the Magnetosphere

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.

Ionosphere Measurements During Cassini's Earth Fly-by

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.

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: 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:
