Multi-Instrument Observations at High Latitudes

The five SSUSI ultraviolet imaging spectrograph instruments are nearly identical to the GUVI instrument on the NASA TIMED mission, though they were built first and flown later. Three SSUSI instruments are operational on DMSP F16, F17, and F18, with the two remaining instruments manifested for F19 (estimated launch in early 2014) and F20. In this work, we compare of SSUSI and GUVI auroral images, maps of average energy and flux, and conductivity to SuperDARN observations during storm times. In particular, we compare the SuperDARN high- and mid-latitude convection patterns to the SSUSI-derived auroral boundary. This work demonstrates the value of using the SSUSI data for independent global observations for SuperDARN to more completely specify the high-latiutde ionosphere.
