AB: The Global Ultraviolet Imager (GUVI) on-board the Thermosphere Ionosphere Mesosphere Energetics and Dynamics (TIMED) satellite has detected far ultraviolet images of plasma depletions in the low latitude and equatorial ionosphere. A model of GUVI observation geometry was developed to simulate radiance observations of a model ionosphere. We report on results in reconstructing multi-dimensional electron density profiles from GUVI brightness measurements through the use of statistical inversion techniques and modeling studies. These electron density profiles can be used to characterize equatorial plasma bubbles. With nearly four years of available GUVI data, there are many coincident observations of equatorial plasma bubbles with ground-based instruments. GUVI electron density images characterize structures also seen in infrared images over Hawaii, JULIA radar images, and other ground-based measurements. Results from these coordinated studies are presented and applied to outstanding science questions of equatorial plasma bubble formation and development.
