"Near Earth Space Plasma Science and Instrumentation" Abstract: The near-Earth space environment presents many challenges to experimenters who wish to measure geophysical parameters using in-situ instrumentation. To address these issues a wide range of instruments have been developed for use on both satellites and suborbital sounding rockets. These effectively complement ground-based radar and optical techniques, and in some cases provide data that cannot be obtained through any other technique. In this talk some methods for making in-situ neutral wind measurements in near-Earth space will be discussed, with a focus on laboratory and flight validation of two new instruments that are slated to fly on the C/NOFS satellite in 2008. Following this introduction to the engineering aspects of the wind instruments, measurements of coupled ion/neutral structuring at midlatitudes will be presented and interpreted in terms of the continuity equation. The results will illustrate the critical role that winds play in midatitude thermospheric physics. January 22, 2008 3:30 pm - 4:30 pm 2246 SRB Auditorium |
