Since its inception, the U.S. Global Change Research Program has had the policy of full and open data availability. This policy has already been implemented not only through the participating agencies but through many inter-agency mechanisms such as publications, Internet based services, and in many international settings.

This fourth of a series of yearly publications represents another important step in this interagency process of making the data and information related to the Global Change Research Program available. It is particularly needed at this time since the users of this data and information have expanded from being primarily researchers to being a full mix that also includes educators, those making assessments of potential effects of global change, the commercial world, and the public as well as policy makers at all levels.

One of this publication’s objectives is to provide this diverse user community with a concise summary of what data has been cataloged and made newly available each year. This is being done in both this published form  and in the Global Change Data and Information System on the Internet ( with links to each data set, where available. Other objectives, however, are also important. These include giving recognition to the individuals and organizations who have done the important job of making the data available and providing a mechanism where the data sets used in a publication or assessment can be cited similarly to the citations now commonly used in publications to reference other publications.

To help the user of this publication find the data in which they are most interested, the data has been separated into subject categories. These categories, with representative topics that each in includes, are below:

  • Agriculture - Crops, Forestry, Livestock, Plants, Soils

  • Atmosphere  - Aerosols, Atmospheric chemistry, Climate, Clouds, Weather

  • Biosphere – Ecology, Vegetation, Wetlands, Zoology

  • Carbon - Atmospheric carbon, Ocean carbon, Sequestration, Soil carbon

  • Cryosphere - Glaciers, Ice, Snow

  • Geology - Earthquakes, Earth’s structure, Gravity, Magnetic fields, Non-renewable resources, Volcanoes

  • Human Dimensions - Economic effects, Environmental effects, Human health

  • Hydrosphere - Ground water, Precipitation, Surface water, Water quality

  • Land Surface - Erosion, Land cover, Land type, Land use, Topography

  • Oceans - Coastal processes, Circulation, Resources, Temperature, Waves

  • Paleoclimate –Historical records,  Ice, land, and ocean cores

  • Solar Physics - Energetic particles, Solar activity, Solar radiation.
