Computational models play an increasingly central role in underpinning our understanding of the environment, society. The DDC contains data produced from Integrated Assessment Models (IAMs), Carbon-cycle Models, General Circulation Models, and Earth System Models.

• Climate System Scenario Tables (Annex II of IPCC 5th Assessment Report, WG1 -- as Excel workbook
• Emissions scenarios (from Integrated Assessment Models):
  • RCP Emissions and Land Use scenarios used in AR5
  • SRES Emissions scenarios used in TAR and AR4
  • IS92 Emissions scenarios user in SAR
• Carbon Dioxide: Projected emissions and concentrations
• Global climate model output
  • Results from GCM-Runs for the Fifth Assessment Report (AR5)
  • Results from GCM-Runs for the Fourth Assessment Report (AR4) based on the IPCC-SRES scenarios
  • Results from GCM-Runs for the Third Assessment Report (TAR) based on the IPCC-SRES scenarios
  • Results from GCM-Runs based on the IPCC-IS92a (or similar) emission scenarios
  • Results from GCM-Runs user in the First Assessment Report (FAR) (subset)
• Global climate model output: period-averages
  • Model output described in the 2007 IPCC Fourth Assessment Report (SRES scenarios)
  • Model output described in the 2001 IPCC Third Assessment Report (SRES scenarios)
  • Model output described in the 1995 IPCC Second Assessment Report (IS92 scenarios)
• Global climate model output: global-means (AR4)
