Our Data Sets & Resources

Climate and Global Dynamics Laboratory facilitates access to extensive collections of climate model output and observational datasets. These products are very popular with climate change researchers, both in the United States and internationally.

Output from the Community Earth System Model and its predecessors is available through these channels:

Observational data sets are used throughout CGD for climate model development, model evaluation, and studies of climate variability and climate change.

  • The Climate Data Guide includes documentation and discussion of many of the most prominent observational data sets, used widely at NCAR and around the world.
  • The Climate Analysis Section's Data Catalog includes numerous climate indices and reprocessed data sets from reanalyses and satellite observations.
  • NCAR-CISL's Research Data Archive maintains an extensive collection of data sets to support atmospheric and geosciences research.
  • NCAR-CISL's Community Data Portal is a collection of earth science data sets from NCAR, UCAR, UCP, and participating organizations.

Additional Data And Data Sets Resources

  • ACACIA: A Consortium for the Application of Climate Impact Assessments (ACACIA) provides sulfur dioxide emissions data.
  • ARCAS: The ACACIA Regional Climate Data Access System (ARCAS) provides access to CSM and PCM datasets via LAS.
  • CESM: Output data is available for Community Earth System Model (CESM) control runs performed to validate each X.0 upgrade.
  • CAS: NCAR's Climate Analysis Section (CAS) in CGD maintains a number of observational data sets and analyses from a variety of sources in support of modeling efforts and climate research. These data have been put on common grids (usually T42 or T63 gaussian grids) to facilitate comparisons.
  • CDAS: Carbon Data-Model Assimilation.
  • CDP: NCAR's Community Data Portal (CDP) is a collection of earth science datasets from NCAR, UCAR, UOP, and participating organizations in the following research areas: oceanic, atmospheric, space weather and turbulence.
  • ESG: The Earth System Grid (ESG) integrates supercomputers with large-scale data and analysis servers located at numerous national labs and research centers to create a powerful environment for next generation climate research.
  • PCMDI: Program for Climate Model Diagnosis and Intercomparison (PCMDI) develops improved methods and tools for the diagnosis and intercomparison of general circulation models (GCMs) that simulate the global climate.
  • CISL Portal: NCAR's CISL Portal provides a customizable web interface to CISL high-end computing resources and information.
  • VEMAP: The Vegetation Ecosystem Modeling and Analysis Project provides a central collection of geographic, vegetation, soil, and site files.
