Carbon Dioxide Information Analysis Center

The Carbon Dioxide Information Analysis Center (CDIAC) is the primary climate-change data and information analysis center of the U.S. Department of Energy (DOE). CDIAC is located at DOE's Oak Ridge National Laboratory (ORNL) and includes the World Data Center for Atmospheric Trace Gases. CDIAC's data holdings include estimates of carbon dioxide emissions from fossil-fuel consumption and land-use changes; records of atmospheric concentrations of carbon dioxide and other radiatively active trace gases; carbon cycle and terrestrial carbon management datasets and analyses; and global/regional climate data and time series. CDIAC provides scientific and data management support for projects sponsored by a number of agencies, including the AmeriFlux Network, continuous observations of ecosystem level exchanges of CO2, water, energy and momentum at different time scales for sites in the Americas; the Ocean CO2 Data Program of CO2 measurements taken aboard ocean research vessels; DOE-supported FACE experiments, which evaluate plant and ecosystem response to elevated CO2 concentrations; and the HIPPO project, which is analyzing the atmospheric carbon cycle and greenhouse gas concentrations from pole to pole over the Pacific Ocean. CDIAC is supported by DOE's Climate and Environmental Sciences Division within the Office of Biological and Environmental Research (BER).

      Global and hemispheric temperature anomalies - land and marine instrumental records. These global and hemispheric temperature anomaly time series, which incorporate land and marine data, are continually updated and expanded by P. Jones of the Climatic Research Unit (CRU) with help from colleagues at the CRU and other institutions. The land portion of the database from which the Jones et al. time series are computed consists of surface air temperature (SAT) data (land-surface meteorological data and fixed-position weather ship data) from over 3000 station records that have been corrected for non-climatic errors, such as station shifts and/or instrument changes (Jones 1994). The marine data used are compiled at the Hadley Centre of the United Kingdom Meteorological Office and consist of sea surface temperatures (SSTs) that incorporate in situ measurements from ships and buoys. The land and marine data components are combined by first interpolating each to the same 5° x 5° latitude/longitude grid boxes. The combined version takes values from each component and weights the grid boxes where both occur (coastlines and islands).
