  1. Integrated Earth System Analysis Workshop Report Held November 2010, Baltimore MD http://www.usclivar.org/Reanalysis2010.php Details at 2PM – POS Panel

  2. IESA Workshop Overview • Evaluation of Reanalyses – Developing an Integrated Earth System Analysis (IESA) Capability November 1-3, 2010, Baltimore (90 Participants) • Assess strengths and limitations of the new recent U.S. reanalyses and suggest where improvements of reanalysis products can be made; identify additional studies necessary to further elucidate the fidelity and usefulness of recent U.S. reanalyses; (DAY 1) • Develop definitions and identify goals of U.S. efforts leading to the forthcoming generation of integrated Earth system analyses (IESA); (DAY 2) • Develop diagnostics to quantitatively assess needed improvements in IESA products; (DAY 2) • Demonstrate applications of reanalyses in climate and weather that would further highlight needed improvements in reanalysis products (DAY 3)

  3. Overall • New reanalyses generally producing improved results over previous • Observing system variations continue to limit climate quality of all reanalyses • Models and observations continue to improve; need to narrow the difference among reanalyses • Multiple reanalyses are more beneficial than burdensome – Improved understanding of the uncertainty (especially important for coupled analyses), quantified impact of certain features

  4. Looking forward • Utilize the multitude of reanalyses: Characterizing the variance among reanalyses (uncertainty?) • Develop the benchmark from which to evaluate new Integrated reanalyses (physics/data assimilation) • Better understand the physics in the reanalysis systems • Present day decadal and climate predictions • CFSR has coupled components; GMAO coupled analysis for NCA under development • Data Limitations and IESA – Pre-Argo Pre-EOS • New reanalyses will continue to be developed, some will be coupled Earth systems • Communication between the user community and those knowledgeable about the systems is essential (e.g. more detailed output diagnostic requirements)

  5. 4th WCRP International Conference on Reanalyses • Silver Spring MD, May 7-11 2012 • http://reanalyses.org/meetings/4th-wcrp-international-conference-reanalyses • Major Topics • IESA and components of the Earth System • Impact of the changing observing system • Validation and Metrics • Observations and Data Assimilation • Applications and International collaborative efforts • Presently developing a list of invited speakers
