Abstract
The synthesis and modeling of ecological processes at multiple spatial and temporal scales involves bringing together and sharing data from numerous sources. This article describes a data and information system model that facilitates assembling, managing, and sharing diverse data from multiple disciplines, scales, and sites to support integrated ecological studies. Cross-site scientific-domain working groups coordinate the development of data associated with their particular scientific working group, including decisions about data requirements, data to be compiled, data formats, derived data products, and schedules across the sites. The Web-based data and information system consists of nodes for each working group plus a central node that provides data access, project information, data query, and other functionality. The approach incorporates scientists and computer experts in the working groups and provides incentives for individuals to submit documented data to the data and information system.

Bibliographical note
Funding Information:One of the projects examined by NRC as an example of a large integrated ecological study is the First ISLSCP (International Satellite Land Surface Climatology Project) Field Experiment (FIFE) funded by NASA (NRC, 1995) . The FIFE project collected intensive remote sensing and field data on a prairie site in Kansas in 1987 and 1989 to better understand fluxes between the land surface and the atmosphere and to develop associated remote-sensing methodologies. The project included 29 teams organized in six disciplinary groups. An extensive collection of FIFE data and metadata were compiled and distributed as a 5-volume CD-ROM set (Strebel et al., 1994a) , and these data are currently available online from the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) World Wide Web home page ( http://www-eosdis.ornl.gov ). The DAAC is the long-term archive for the data. The FIFE information system was also used to demonstrate the implementation of a conceptual framework for scientific information systems (Strebel et al., 1994b) .
