The SSUSI (Special Sensor Ultraviolet Spectrographic Imager) instrument on-board the DMSP F16 satellite has global observations of the ionosphere at 8 PM local time during 2004—2009. An existing tomographic reconstruction code has been modified to produce a 3-D electron profile from UV brightness observations. The Cornell Narrow Field Imager (CNFI) at Haleakala, Hawaii also has observations of plasma bubbles throughout the night during 2002—2009. Coordinated observations of plasma bubbles using these different imaging modalities enhance understanding of the morphology of plasma bubbles and the characteristics of the background ionosphere. Detailed comparisons of observed ionospheric features are used for validation of the 3-D electron density reconstructions. Details of the reconstruction and imaging techniques are presented, along with a discussion of the capabilities and limitations of each observing platform. The feasibility of using ground-based measurements to augment and constrain the three-dimensional reconstructions is also discussed.
