Research Goals:
The goal of the EOSDIS program is to make global change data and information easily available to global change researcher and other users. Like all data and computing capabilities, EOSDIS is not an end in itself but a means to facilitate the research. As such, the key to success for EOSDIS and the policy framework which accompanies it is to respond to the needs of the large user community and to encourage cooperation.

Research Description:
EOSDIS is one of NASA's contributions to the national interagency Global Change Data and Information System (GCDIS) for the archive and distribution of data and information related to Earth and how it is changing. EOSDIS is itself being developed as a distributive system, in response to the requirements of global change researchers and earth system scientist. The open architecture of EOSDIS facilitates interaction with similar data systems of other agencies and countries. NASA's EOSDIS activities concentrate on improved availability and use of existing data sets within the initial years, in advance of receipt of larger capabilities required to handle data flow from the full suite of EOS instruments which will be at an average rate exceeding 2 megabytes per second (roughly equivalent to 250 million pages of a text book a day). Additionally, EOSDIS includes the elements of EOS flight system planning and ground operations.

Program Interfaces:
The program is vital to scientist around the world doing global change research. It is coordinated with other federal agency global change information systems through the Committee on Earth and Natural Resources (Committee on Environment and Natural Resources (CENR)) Subcommittee on Global Change Research (SGCR) and international coordination through the Committee on Earth Observation Satellites (CEOS).

Program Milestones:
The first release of EOSDIS Version 0 was July, 1994. PDR is December, 1994 and CDR will be Mid 1995 with Version 1 released in December 1996 to allow a period of use and comment.

Policy Payoffs:
A better understanding of the extent, causes, and regional consequences of global change.
