The Carbon Dioxide Information Analysis Center (Thomas A. Boden, Director), which includes the World Data Center for Atmospheric Trace Gases, has served as the primary climate-change data and information analysis center of the U.S. Department of Energy (DOE) since 1982.
CDIAC responds to data and information requests from users worldwide investigating the greenhouse effect and global climate change. CDIAC's data holdings include records of the concentrations of carbon dioxide and other radiatively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.
On the other hand, CDIAC does not archive computer model output or specialize in information on the medical aspects of carbon dioxide exposure, or industrial and household uses of carbon dioxide (for example, commercial sources of canisters of compressed CO2 gas, or fire extinguisher supplies).
CDIAC is supported by DOE's Climate and Environmental Sciences Division of the Office of Biological and Environmental Research. CDIAC represents DOE in the multi-agency Global Change Data and Information System. Dr. Wanda Ferrell is DOE's Program Manager with responsibility for CDIAC.
