WDAC background material for JSC 34

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. ).

WDAC 2 Darmstadt, 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

WDAC 2 Darmstadt, 4 -5 March • Data sets quality assessments: plan blue-print on best practices, GEWEX will initiate with inputs from WCRP core projects and others • obs 4 MIPs: agreement on establishment of panel to internationalize the activity, To. Rs and membership to be fine-tuned • WDAC 3, Gallway, Ireland, 2014

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

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

WCRP 4 th 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

WCRP 4 th International Conference on Reanalysis • • • See report to last WDAC for some details The full conference report at icr 4. org, available A brief summary is accepted to BAMS ICR 4 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

CMIP 5 Coupled Model Intercomparison Project A rich set of modeling experiments, drawn from several predecessor MIPs, focuses on model evaluation, projections, and understanding • • • Red matches CMIP 3 experimental suite Green coupled carboncycle climate models 1+ Petabyte on Earth System Grid 59 models, 24 groups Many studies contributing to the IPCC AR 5 report Already 250+ papers Other modeling efforts within WCRP (Seasonal-to-internannual, Decadal, Regional-CORDEX) will most likely follow similar scheme in the future

Coordinated Regional Climate Downscaling (CORDEX) • 12 domains with a resolution of 0. 44° (approx. 50 x 50 km²), focus on Africa • High res ~0. 11°x 0. 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 (50 km 2) reproduces well the mean annual malaria incidence pattern with respect to TRMM-ERAINT & GPCP-ERAINT control experiment Nikulin, G. , et al, J. Clim, 2012

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 1 st day: High Level Session, Stakeholder dialogue 2 -4 th days: Scientific Conference http: //cordex 2013. wcrp-climate. org/ Deadline for abstracts: 15 April

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

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

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

Earth System Grid Federation

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

Intercomparison Models-Observations Coordinated with CMIP 5 are parallel efforts to collect and make available observationally-based products Obs 4 MIPs A pilot effort to improve the connection between data experts and scientists involved in climate model evaluation. Aligned with CMIP 5, 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 Obs 4 MIPs such as cryosphere, biogeochemistry, etc.
