  1. WDAC background material for JSC34

  2. WCRP Data Advisory Council (successor to WOAP) Mission • act as a single entry point for all WCRP data, information, and observation activities with its sister programmes, • coordinate their high-level aspects across the WCRP, • ensure cooperation with main WCRP partners such as GCOS, CEOS, CGMS and other observing programmes WDAC will work with the WCRP Modeling Advisory Council to promote effective use of observations with models and to address issues related to the coordinated development of data assimilation, reanalysis, Observing System Sampling Experiments, fluxes and paleoclimatic data and their assessments (metrics, etc.).

  3. WDAC2Darmstadt, 4-5 March • Inventories: joint CEOS/CGMS – GOSIC tool; QA/QC; WCRP core programs, GCOS panels and WMO to solicit inputs • Reanalysis: Task Team to plan “Observations for Reanalysis” Workshop for 2014 • RRR: need improved mechanism to reframe requirements from WDAC perspective

  4. WDAC2Darmstadt, 4-5 March • Data sets quality assessments: plan blue-print on best practices, GEWEX will initiate with inputs from WCRP core projects and others • obs4MIPs: agreement on establishment of panel to internationalize the activity, ToRs and membership to be fine-tuned • WDAC3, Gallway, Ireland, 2014

  5. WCRP-GCOS • WCRP depends on Observing Programs to advocate for improving and sustaining the existing networks and establish new measurements (e.g. deep oceans, upper atmosphere, cryosphere, interfaces) • WCRP coordinates research on climate for understanding the underlying processes, studying the trends, developing integrated observing systems and, improving and validating climate predictions

  6. Some examples of WCRP research that rely on data • Reanalyses • Data assimilation • Initialized predictions • Observing system simulation experiments • Process studies • Model development • Model evaluation • Climate Assessments

  7. WCRP 4th International Reanalysis Conference May 7-11, 2012 Silver Spring, Maryland USA 270+ participants (including GCOS participation) [42 countries] Agency Priorities: An Open Panel Discussion with Conference Participants • Quantitative Uncertainty Estimation: • families of reanalyses • Qualitative Uncertainty Estimation: • reanalysis.org, climatedataguide.ucar.edu • Earth System Coupling: • interdisciplinarity, synergies between communities • Reanalyses, Observations and Stewardship: seamlessness of data discovery and access, ESG

  8. WCRP 4th International Conference on Reanalysis • See report to last WDAC for some details • The full conference report at icr4.org, available • A brief summary is accepted to BAMS • ICR4 was initiated through WOAP and oversight continues through WDAC • Next conference should be within 4-5 years, or 2016-2017 (with about 2 years lead up) • Input Observations collaborations and organization - forthcoming workshop

  9. CMIP5Coupled Model Intercomparison Project A rich set of modeling experiments, drawn from several predecessor MIPs, focuses on model evaluation, projections, and understanding • 1+ Petabyte on Earth System Grid • 59 models, 24 groups • Many studies contributing to the IPCC AR5 report • Already 250+ papers • Other modeling efforts within WCRP (Seasonal-to-internannual, Decadal, Regional-CORDEX) will most likely follow similar scheme in the future Red matches CMIP3 experimental suite Green coupled carbon-cycle climate models

  10. Coordinated Regional Climate Downscaling (CORDEX) •12 domains with a resolution of 0.44° (approx. 50x50km²), focus on Africa •High res ~0.11°x0.11° for Europe (by some institutions) Dynamic Malaria Model driven by climate observations & CORDEX simulations (mean annual prevalence (%) Example of CORDEX multi-model data available for Africa. From Top to bottom and left to right: GPCP mean July-August-September precipitation for 1998-2008 and differences compared to GPCP in the other gridded observations, and the individual RCMs with their ensemble average. SMHI (50km2) reproduces well the mean annual malaria incidence pattern with respect to TRMM-ERAINT & GPCP-ERAINT control experiment Nikulin, G., et al, J. Clim, 2012

  11. International Conference on Regional Climate - CORDEX 2013 • 4-7 November 2013, Brussels, Belgium • Partnership between WCRP, IPCC and EC • Timed between IPCC WGI and WGII releases • 1st day: High Level Session, Stakeholder dialogue • 2-4th days: Scientific Conference • http://cordex2013.wcrp-climate.org/ • Deadline for abstracts: 15 April

  12. Trends – new requirements • From Climate Models to Earth System Models (including ocean, land, cryosphere, stratosphere, biosphere, etc) • From Global Climate Models to Regional Climate Models • From Models to Impacts, Vulnerability, Adaptation and Mitigation • Increased resolution and interdisciplinarity… and expectations on discovery, seamlessness, consistency, relevance, quality, etc

  13. Essential tools • Discovery: inventories • Seamlessness: data grid • Standards: conventions • Mining: intelligent archives • QC&QA: assessments • Evaluation: metrics

  14. GOSIC Portal • One stop shop data access for GCOS, GOOS, GTOS and partner programs by: • ECVs (matrix) • Program • Observation (Atmospheric Surface, Upper Air, Radiation, Observations, etc.) • Individual networks (GSN, GUAN, etc.) • Joint programs with GOOS & GTOS • Regional Activities (US GCOS) • Societal Benefit Areas • Metadata • …. http://GOSIC.org

  15. Earth System Grid Federation

  16. Federation connectedness means the user does not have to know where the data resides and critical data is replicated

  17. Intercomparison Models-Observations Coordinated with CMIP5 are parallel efforts to collect and make available observationally-based products Obs4MIPs A pilot effort to improve the connection between data experts and scientists involved in climate model evaluation. Aligned with CMIP5, with encouragement from the WGCM, WGNE, WDAC. NASA and the U.S. DOE have initiated the project with significant contributions of appropriate NASA products. Communities to contribute data to Obs4MIPs such as cryosphere, biogeochemistry, etc.

  18. Model and Observation Overlap Initial Data Sets and Ongoing Efforts Initial Phase 1 1 1 1 1 ~4 1 1 1 ~6 1 1 3 • Present efforts are working to provide: • CFMIP cloud-related products (much of this completed) • MISR (land) and MODIS (ocean) AOD • Sea Ice (NSIDC) • CALIPSO Aerosol Optical Extinction Profile • CERES surface radiation budget • MODIS Land (e.g. albedo, LAI, FPAR) Continued Discussions with ESA’s CMUG & CEOS Climate Working Group to expand holdings.
