  3. Ravens The “Quaff B” Scenario “Ravens +” Quaff B Quaff A at L1 The Quaff mission could incorporate the Ravens instrument complement on two Quaff B satellites. “Ravens on Quaff” would be a powerful addition to the ILWS program, providing the only global imaging in ILWS, monitoring the IT consequences of disturbances of solar origin, and delivering numerous technical and scientific firsts. 2004/12/09

  5. process Sink Source Ravens on Quaff ILWS The overarching objective of ILWS is to explore how solar variability affects the Earth environment in the short and long term. ILWS will explore physical processes in the sun-Earth system, focusing on those with planetary-scale effects, and will quantify the geoefficiency of coupling processes. To accomplish this, we need quantitative observations of the source (such as the solar wind or solar EUV), detailed and comprehensive observations of a geospace process that is of interest, and quantitative observations of sinks (such as the plasmasphere, ionosphere, thermosphere, ring current, & convection). 1 2004/12/09
