Carbon Dioxide Information Analysis Center (CDIAC)


Carbon Dioxide Information Analysis Center (CDIAC) is the primary climate-change data and information analysis center of the US Department of Energy (DOE).

Its 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 data management support for major projects, 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 NARSTO, which assesses ozone and fine particle processes in the troposphere over North America.
