ISS FPMU Observations of Ionospheric Plasma Variability
Abstract
The Floating Potential Measurement Unit (FPMU) is a suite of plasma instruments operational on the International Space Station (ISS) since August 2006. The ISS altitude is maintained near 400 km providing a long-term opportunity for equatorial and mid-latitude observations of the ionosphere plasma density and electron temperature F-region and above. This presentation will highlight examples of density and temperature variations sampled by the FPMU along the ISS orbit including climatological features of the ionosphere such as the equatorial plasma crests and day/night variations in plasma density and temperature. In addition, examples of dynamic variations in plasma density and temperatures will be discussed including those associated with geomagnetic storms and the occurrence of equatorial plasma instabilities including bubble structures. Opportunities for collaborations and accessing the FPMU data will be described.
