1. 3. Reanalysis Report Michael Bosilovich, Pierre Gauthier, Adrian Simmons, Detlef Stammer and Russel Vose

2. Joint Reanalysis Data Working Group Reanalysis Input Catalog – Recommend to go forward – Include quality review – Support disciplinary input data sets (also contributes to preparation for coupled reanalyses) – Link to reanalyses output (obs, forecast error, analysis error, etc) Recommend to concentrate on in-situ observations maintenence (satellite obs, radiances and retrievals have stewards)

3. WCRP Reanalysis Pamphlet Generally supported, but needs champion Should encompass all disciplinary reanalyses An Introductory description on the purpose of the pamphlet First Step, request for information (template) – Project Name (Contact) – Specs (time,space domain) – Unique features or objectives – Future planning

4. 4 th International Reanalysis Conference Some agreement on early April 2012 – not too close to WCRP Science Conference? – Will check WCRP calendars Will work with David Legler? and NCEP on developing the local organizing committee Program committee M. Bosilovich (Chair, Climate/Weather studies) D. Stammer (Ocean/Ice) A. Simmons R. Vose (in situ Obs) K. Trenberth? (Climate Dynamics/Variability, GEWEX) JRA NCEP ESRL (Compo or Whitaker) Data Assimilation (D. Dee, ECMWF) Land Analysis (T. Koike, or others) Sat Ob. (J Bates) WGNE (C. Jakob? modeling, parameterization) WCRP (G. Asrar) ? – Already invovled in the Open Sci. Conf.

5. Atmospheric Reanalysis Proliferation Generally, a sign of a strong growing community At this time, take advantage of multiple data sets Consider outcome of the Technical Workshop on metrics discussions Possible project to mitigate user questions: Coordinated Assessment of Reanalyses – When you consider space/time/variable dimensions, the project is huge – Manpower issues – Center participation, Independent lead (and/or PCMDI to facilitate assessments, analogous to AMIP CMIP exps.) – Perhaps a community wiki?
