The National Oceanic and Atmospheric Administration (NOAA) collects, manages, and disseminates a wide range of climate, weather, ecosystem and other environmental data that are used by scientists, engineers, resource managers, policy makers, and others in the United States and around the world. The increasing volume and diversity of NOAA's data holdings - which include everything from satellite images of clouds to the stomach contents of fish - and a large number of users present NOAA with substantial data management challenges. NOAA asked the National Research Council to help identify the observations, model output, and other environmental information that must be preserved in perpetuity and made readily accessible, as opposed to data with more limited storage lifetime and accessibility requirements. This report offers nine general principles for effective environmental data management, along with a number of more specific guidelines and examples that explain and illustrate how these principles could be applied at NOAA.

The report outlines key elements to consider in designing a program to create climate-quality data from satellites. It examines historical attempts to create climate data records, provides advice on steps for generating, re-analyzing, and storing satellite climate data, and discusses the importance of partnering between agencies, academia, and industry. NOAA will use this report-the first in a two-part study-to draft an implementation plan for climate data records.

The report reviews the National Geophysical Data Center (NGDC) and assesses how well the center is managing its holdings, serving its users, and supporting NOAA's mission. It concludes that NGDC is the natural place within NOAA and the nation for stewardship and dissemination of data related to the solid Earth and space environment. These subject areas are also relevant to NOAA's new priority on integrated environmental approaches. For NGDC to fulfill its potential, however, it must first rearticulate its mission and overcome some solvable problems, including obtaining effective feedback from its users and organizing the center to eliminate parallel activities and reduce scientific isolation among the divisions.
