AB: The NAS Solar and Space Physics Decadal Survey has recommended that the next major ground-based instrumentation initiative for space science research be the deployment of widely-distributed arrays of small instrumentation. Such arrays will provide continuous real-time observations of Earthspace with the resolution needed resolve mesoscale phenomena and their dynamic evolution. Ground-based arrays will address the need for observations to support the next generation of space weather data-assimilation models and will push our understanding of the physical processes which interconnect the spheres of Earthspace to a new level. It is envisioned that DASI instrumentation will provide real-time data for a wide variety of research, applications, and educational users. Infrastructure issues including instrument design and deployment, communications, and data distribution will be important aspects of a DASI plan. In order to provide a strong foundation for future initiatives addressing the DASI goals, the NAS Committee on Solar and Space Physics (CSSP) has undertaken a study of the scientific need for such arrays, the infrastructure needed to support and utilize them, and an implementation plan for their deployment. Community input was solicited in the spring of 2004 and a working group meeting was held at the NAS Woods Hole facilities in June, 2004 to discuss a science plan for DASI and to address issues for inclusion in a DASI report. The focus of the CSSP report is the compelling science which will be enabled by the development of arrays of small instruments. The current status and an outline of the DASI science report will be reviewed.
