 [This workshop is followed by the Third Atmospheric Circulation Reconstructions over the Earth (ACRE) Workshop, Nov 4-5]

Retrospective-analyses, or reanalyses, comprise the combination of state of the art models and assimilation methods with highly quality controlled observations, yielding globally continuous data with supporting output diagnostics produced from the model physical parameterizations. The initial reanalyses have proved to be extremely useful data sets for the study of weather and climate variability.  For example, atmospheric reanalyses have also provided forcing and boundary conditions for other components of the Earth system, such as ocean and land models and data assimilation systems. Also, ocean reanalyses have been applied to research in ocean circulation and climate as well as in biochemistry, eco-systems, and geodesy. Subsequent reanalyses have improved upon the models and assimilation techniques, and the observational data sets likewise have improved through quality control.  Presently, new atmospheric, oceanic and land reanalyses are coming available from NASA, NOAA, and other institutions. 
Reanalyses continue to evolve, and in the next generations of reanalyses, coupling between components of the Earth system will be more prominent. Quantifying the uncertainty and improving the quality of reanalyses is increasingly important, both for current and new developing reanalysis efforts. This workshop aims to promote the understanding and assessment of the current reanalyses and to discuss future directions.


Workshop objectives:

  • 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;
  • Develop definitions and identify goals of U.S. efforts leading to the forthcoming generation of integrated Earth system analyses (IESA);
  • Develop diagnostics to quantitatively assess needed improvements in IESA products; and
  • Demonstrate applications of reanalyses in climate and weather that would further highlight needed improvements in reanalysis products

The workshop welcomes contributions in the following areas:

  • Assessment of the scientific strengths and limitations of the latest reanalyses, including for example: NASA MERRA, NOAA CFS, NOAA-CIRES 20th Century Reanalysis, NOAA GFDL coupled, SODA, ECCO.
  • Applications of and requirements for reanalyses to support climate and weather research
  • Efforts to move forward toward integrating (either directly through coupled assimilation or through co-varying products) multiple components of the Earth system (Atmosphere, Ocean, Land, Cryosphere, Chemistry, Carbon, etc.) in reanalyses.

The workshop is intended to bring together reanalysis developers and reanalysis users, and also to bring together various discipline specific analysis systems (including atmosphere, ocean, sea ice, land, and carbon). The anticipated result from the workshop would be improving two-way communications among the reanalysis developers and the climate and weather community, and increasing coordination among developers of the reanalyses for different components.

Logistics

TRAVEL SUPPORT FOR THE REANALYSIS/IESA WORKSHOP
Please note there is a limited amount of funding available to offset travel to support students, postdocs, and/or early career scientists (receiving a PhD after Jan 1, 2008) from US institutions. If you are interested in support, please provide your name, institution and the type/amount of support you are requesting along with a vita and abstract for presentation at the workshop. A short letter confirming your affiliation should also be provided if you are a student. Please be aware federal employees are NOT eligible to receive funding.

Please submit this information by September 30, 2010.
