Evaluation
of Reanalyses – Developing
an Integrated Earth System Analysis (IESA) Capability
November 1-3, 2010,
Sheraton Hotel, Baltimore, Maryland (Inner Harbor)
Online
registration available - abstract deadline 10 September 2010
Agenda now online
Sponsors: NOAA, NASA, NSF, and U.S. CLIVAR
[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.
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.
