DEVELOPMENT OF THE DATA AND INFORMATION SYSTEM FOR THE EARTH OBSERVING SYSTEM (EOS) E. G. Njoku* Earth and Space Sciences Division Jet Propulsion Laboratory Pasadena, CA 91109, USA G. W. Hunolt G. H. Ludwig Earth Science and Applications Division National Aeronautics and Space Administration Washington, DC 20546, USA T. T. Taylor Earth Observing System Project Office Goddard Space Flight Center Greenbelt, MD 20771, USA ABSTRACT The Earth Observing System (EOS) is the centerpiece of NASA's participation in the U.S. Global Change Research Program. The goals of the EOS mission are to provide an observing system to acquire global Earth science data on a long-term, sustained basis, and to provide the capabilities for processing these data into scientifi cally validated products. These processed data will in turn provide the basis for studies of Earth system science - the physical process studies, global modeling, and environmental monitoring which are essential for understanding and predicting global change. A central requirement of the EOS program is the development and implementation of a comprehensive data and information system which will provide the Earth science community with easy, affordable, and reliable access to the full suite of Earth science data and products from the Eos mission. The EOS Data and Information System (EOSDIS) will provide capabilities for command and control of the EOS instruments on NASA's polar-orbiting platforms, with first platform launch scheduled for 1997. EOSDIS active archive facilities will handle the processing, archiving, and distribution of data for the duration of the fif teen year EOS mission. The early EOSDIS design and development activities are discussed here, with reference to a candidate architectural framework, existing capabilities, and transition steps towards full implementation of the final dis tributed system. KEY WORDS: Data, Information, Earth observation, Remote sensing 1 EOS MISSION 1.1 Historical Perspective The EOS mission is a continuation of a series of NASA Earth observations missions carried out over the past two decades. In recent years the launches and operations of Seasat (1978), Nimbus-7 (1978), SIR-B (1984), and ERBS (1984) missions, to name just a few, have provided a strong foundation of spaceborne remote sensing data for studies of the Earth's oceans, atmo sphere, and land surfaces. In the coming years, prior to the first platform launch of EOS, NASA plans include the launches of ATLAS (1991, -), TOMS (1991, -) , UARS (1991), LAGEOS (1991), TOPEX (1992), SIR-C/X-SAR (1992, -), Sea-WiFS (1993), and NSCAT (1995). These spaceborne mis sions, together with operational (NOAA), commer cial (Landsat), and international space missions, and a supporting program of aircraft, balloon, ground, and laboratory experiments, will provide the basis on which data from the EOS mission will build (NASA, 1988a) . In this context, EOS may be viewed as providing improve ments and continuity for existing measurements in addition to providing new observations of phenomena that have not previously been mea sured. In addition, EOS will provide a compre hensive, global, mapping capability for these measurements, which will remain in place for at least fifteen years to enable a more detailed and complete understanding of our global envi ronment (NASA, 1988b). The EOS Data and Infor mation System (EOSDIS) constitutes the in frastructure of the EOS mission, and will pro vide scientists and managers with access to the full suite of capabilities necessary to acquire, process, store, analyze, and distribute EOS data, as well as access to archives containing non-EOS data. Major challenges for EOSDIS lie in providing a complete information system that can accommodate the high data rates and data volumes from EOS, in improving the productivity of scientists in extracting new knowledge from the remotely sensed data, and in improving the quality and documentation of processed data such that their utility and information content will increase with time. 1.2 Mission Outline EOS is an international, cooperative program in cluding five polar platforms and their follow- ons : two provided by NASA, two by the European Formerly with the Earth Science and Applications Division, Washington, DC 20546, USA. ^gg National Aeronautics and Space Administration,
