Description: The purpose of this report is (1) to define the need for a nationally focused program to generate routinely research-quality, model-assimilated geophysical data sets and (2) to outline a basic strategy to implement an integrated national geophysical archive system to ensure the availability of such data sets to serve a broad range of national needs. The report concisely surveys the current applications and usefulness of research and operational model-assimilated atmospheric and oceanic data sets, assesses current activities for the development of model assimilation technology and new applications, and identifies the pressing national need in the 1990s - to manage and utilize effectively the overwhelming volume of earth system data already scheduled from greatly enhanced ground-based and satellite observing systems. A basic strategy for the earth system sciences is outlined, namely to use the power and consistency of proven model assimilation technology to generate routinely assimilated geophysical data sets in an integrated national geophysical archive system designed to ensure the ready availability of these data sets to the scientific and public policy communities.
