Precision spectropolarimetry with a SOLIS network affords the possibility of monitoring the evolution of solar surface vector magnetic fields as toroidal flux rope systems, created through dynamo action at the base of the solar convection zone, rise buoyantly through the visible solar surface. Local helioseismology, employing data from ground- and space-based oscillation experiments, may be capable of detecting submerged magnetic flux before it reaches the visible solar surface.

SMT programs will be designed to: identify and understand the physical processes that control how magnetic fields are generated in the solar interior, rise to the surface, and evolve after emergence; use this understanding to synthesize a new global paradigm for the operation of the solar cycle; and produce quantitative models relevant to the development of science-based forecasting tools for solar activity and space weather. COMPONENTS OF THE SMI PROGRAM The SMI Steering Committee would work closely with the solar physics community to determine scientific priorities within the program through the establishment of Focus Programs, observing campaigns, and workshops, and through outreach activities such newsletters and presentations at scientific meetings and workshops.

The Corona and Heliosphere How do magnetic fields emerge from below and reverse the polarity of the global magnetic field in this voluminous part of the solar atmosphere? How do the many coronal phenomena (helmet-streamers, prominences, coronal holes, active regions; coronal heating; violent eruptions: flares, prominence eruptions, coronal mass ejections; differential rotation of coronal structures; and magnetic flux emergence)

will support observational efforts in two modes: addressing the scientific basis for developing new ground- and space-based instrumentation; and providing support for independent research efforts to explore diagnostic techniques. In addition to the SOLIS observing network of three stations, which will provide a breakthrough in continuous and precise measurements of the solar vector magnetic field, the SM!

The SMI Committee understands that a national effort will be made to restore U.S. competitiveness in supercomputing, under the name "Terascale and Petascale Computing: Digital Reality in the New Millennium." Given the need to substantially increase computing capacity for demanding scientific research applications, the SMI Committee strongly advocates this national initiative.
