AB: Decades of global-scale terrestrial imaging from space at far-ultraviolet wavelengths have provided many examples of solar- and geomagnetic storm-driven disturbances of the ionosphere/thermosphere system. However, in most cases the monitoring of ionospheric and thermospheric emissions has been a secondary mission goal, with auroral imaging taking precedence. Only recently have routine measurements of the state of the ionosphere and thermosphere through remote FUV imaging become a top science focus of missions such as TIMED. Measurements like these, along with years of dayside and nightside measurements of the FUV emissions of atomic oxygen by IMAGE/FUV have provided the best global picture of solar flare, substorm, and magnetic storm effects on the I-T system to date. The great utility of a high-altitude global imager is to provide continuous measurements for comparisons with data from satellites in low-earth orbit making periodic in-situ measurements. This was demonstrated during the Dynamics Explorer mission of the 1980s, and more recently in coordinated studies of space weather effects in the ionosphere and thermosphere, using data from the ROCSAT 1 and CHAMP satellite missions, respectively. Examples from these and other recent studies relevant to multiple sub-disciplines of I-T science will be discussed. These examples demonstrate the relevance and value of the LWS FUV imager to the proposed LWS I-T Storm Probes mission.
