From page 1...
... As the 2002 decadal survey and other related NRC reports have noted,2 understanding and monitoring the fundamental processes responsible for solar-terrestrial coupling are vital to being able to fully explain the influence of the Sun on the near-Earth environment. These studies emphasize that monitoring the spatial and temporal development of global current systems and flows; the energization and loss of energetic particles; and the transport of mass, energy, and momentum throughout the magnetosphere and coupled layers of Earth's upper atmosphere is essential to achieving this scientific goal.

... Also, it is now becoming clear that a significant fraction of the flow of mass, momentum, and energy in the M-I-T system occurs on relatively small spatial scales and over a wide range of temporal scales. Consequently, elucidation of the fundamental coupling processes requires continuous, coordinated, real-time measurements from a distributed array of diverse instruments, as well as physics-based data assimilation models.

... Other information technology capabilities of note included the use of Internet and computer grid technology and high-data-rate, nearreal-time communications systems. Finally, the workshop illuminated logistics considerations for the DASI concept, including key instrument spacing and size requirements for some classes of instruments as well as opportunities for and constraints on instrument placement in key locations for realizing DASI science objectives.
