  1. ESG Observational Data Integration Presented by Feiyi Wang Technology Integration Group National Center of Computational Sciences

  2. The Need for ESG: Climate Science Data Sharing

  3. ESG-CET Federation Team ESG Sponsors Current ESG Sites http://pcmdi3.llnl.gov/esgcet/home.htm http://esg.ucar.edu/home.htm http://esg2-gw.ccs.ornl.gov/esgcet/home.htm ORNL LLNL NCAR NASA

  4. ESG’s Broad Use • Serving a wide range of model data • Coupled Model Intercomparison Project, Phase 3 (CMIP-3) • Community Climate System Model (CCSM) • Parallel Climate Model (PCM) • Parallel Ocean Program (POP) • The North American Regional Climate Change Assessment Program (NARCCAP) • Cloud Feedback Model Intercomparison Project (CFMIP) • Carbon-Land Model Intercomparison Project (C-LAMP) • LLNL CMIP-3 (IPCC AR4) ESG portal • 35 TB of data at one location • 83,337 files, model data from 13 countries • Generated by a modeling campaign coordinated by the Intergovernmental Panel on Climate Change (IPCC) • ORNL (C-LAMP, CCSM Data) ESG portal • 71 TB of data at one location • 270,378 files • Includes all model data generated by he Carbon Land Model Intercomparison Project (C-LAMP) • CDIAC and ARM • NCAR CCSM ESG portal • 237 TB of data at four locations (NCAR, LBNL, ORNL, LANL) : 965,551 files • Includes the past 7 years of joint DOE/NSF climate modeling experiments • Broad Impact • Over 2,700 sites • 20,000 users • 120 countries • Over 1 PB downloaded • 500 – 800 active users in a given month • Over 600 published papers • Courtesy: Gary Strand - NCAR

  5. ESG: All About Federation

  6. Carbon-Land Model Inter-comparison Project (C-LAMP) – An Exemplar Allows the scientific community to evaluate the performance of biogeochemical models normally coupled to general circulation models (GCMs). Established metrics to evaluate model performance via observational dataset inter-comparison • Courtesy: Jamison Daniel- ORNL • Courtesy: Forrest Hoffman- ORNL

  7. Publishing High Impact Observational Data • CDIAC • AmeriFlux (L2) • AmeriFlux (L4) – When available • Gridded Fossil Fuels • ARM • Climate Modeling Best Estimate • Atmospheric Quantities • Cloud and Radiation Quantities

  8. ARM – Climate Modeling Best Estimate File collection Harvested metadata 1 Top level project 3 Nested collections & datasets 2

  9. CDIAC – AmeriFlux Level 2

  10. ESG Integration: Next Steps • Support search of non CF-compliant variables • Spatio-temporal search support • ORNL will lead this effort in the ESG community • More flexible data model • In collaboration with NCAR and NASA JPL • Enhanced search API and web intelligence • Support both RDF triple store and Next Generation Search Technologies • Flexible data publishing workflow • Incremental, continuous, automated agents • In collaboration with LLNL • Soliciting feedback on CDIAC user community requirements

  11. Synergistic Activities – UV-CDAT • The Ultra-scale Visualization – Climate Data Analysis Tools (UV-CDAT) • An integrated framework for end-to-end data analysis and visualization of climate model and observational datasets • Provenance, Workflow and automated inter-comparison (both model/model and model/observations)

  12. Summary • We published several high impact observational datasets and made them available to a broader community • We made good progress on identifying the limitations of the current system and identifying areas of improvement • We have developed a path forward to fully integrate high-impact Observational Datasets within ESG • We developed a collaborative relationship between the ESG and observation dataset community and are playing an active role in extending ESG to support their requirements
