JCSDA Management Structure
JCSDA Science Workshop, UMBC, 05/12-13/2009
JCSDA Science Priorities
Radiative Transfer Modeling (CRTM) Preparation for assimilation of data from new instruments Clouds and precipitation Assimilation of land surface observations Assimilation of ocean surface observations Atmospheric composition; chemistry and aerosol
Driving the activities of the Joint Center since 2001, approved by the Science Steering Committee
Overarching goal: Help the operational services improve the quality of their prediction products via improved and accelerated use of satellite data and related research
JCSDA Science Workshop, UMBC, 05/12-13, 2009
New JCSDA short-term goal:(adopted 03/2008)
• “Contribute to making the forecast skill of the operational NWP systems of the JCSDA partners internationally competitive by assimilating the largest possible number of satellite observations in the most effective way”
JCSDA Science Workshop, UMBC, 05/12-13/2009
From idea to implementation (R2O)
Basic research Applied research Research to Operations
transition (JCSDA) Operational implementation (NCEP,
AFWA, FNMOC, …)
JCSDA Mode of operation
• Directed research– Carried out by the partners– Mixture of new and leveraged funding– JCSDA plays coordinating role
• External research– Historically implemented as a NOAA-administered FFO, open to
the broader research community– Typically ~$1.4 M/year available => revolving portfolio of ~15 three-
year projects
• Results and progress from both directed and external work reported at JCSDA Science Workshop (May 12-13, 2009)
JCSDA Science Workshop, UMBC, 05/12-13, 2009
Directed Research, JCSDA Working Groups
• Composed of working level scientists from (in principle) all JCSDA partners, plus additional members where appropriate
• Tasked with sharing information and coordinating work where possible
• Roles and scope still under evolution• Four WGs formed so far
– CRTM– IR sounders– Microwave sensors– Ocean data assimilation
JCSDA Science Workshop, UMBC, 05/12-13, 2009
External Research Program• Complements internal efforts and expertise of JCSDA partners, e.g.
– CRTM upgrades, spectroscopy, algorithms– Clouds and precipitation
• Engages research community in R2O transition activities of vital national importance, e.g.– Data assimilation methodology– Diagnostics of data impact and model performance
• No announcement in FY 2009 due to lack of funds• FY 2010 announcement is on track
– Program will be split between grants and contracts (NOAA and NASA, respectively)
– Longer term plans still being worked out

COSMIC: recent impact
AC scores (the higher the better) as a function of the forecast day for the 500 mb gph in Southern Hemisphere
40-day experiments:– expx (NO COSMIC)
– cnt (operations - with COSMIC)
– exp (updated RO assimilation code - with COSMIC)» Many more observations
» Reduction of high and low level tropical winds error
COSMIC provides 8 hours of gain in model forecast skill at day 4!!!!

JCSDA Science Workshop, UMBC, 05/12-13, 2009
JCSDA Advisory Panel 01/2009 Dr. James F.W. Purdom (Panel Chair) on JCSDA FFO:
“We are concerned with the decreased funding of the Federally Funded Opportunity (FFO) program, as it is the gateway to the academic community. We recommend continuing to fund the FFO as a grant and offering the most promising FFO research a contractual arrangement to move toward operational implementation”
JCSDA Science Workshop, UMBC, 05/12-13, 2009
JCSDA Advisory Panel 01/2009.Prof. Rick Anthes on satellite data research:
“The national investment in satellite data assimilation is a tiny fraction of the investments in the satellite systems themselves, yet assimilation research and implementation in operational models are essential to realize the enormous potential of the satellite data. Augmented investments in data assimilation research and the supporting computing tools are highly recommended”

Questions to the Workshop
(breakout groups): In light of what you have seen and heard from oral and
poster presentations during this Workshop, how would you rate the JCSDA activities in your subject areas?
What should be the top priority for your subject area if additional funding were to become available?
Internal, external? Are there data types or subject areas where JCSDA is
missing the boat? What is the role of your JCSDA Working Group?
If you don’t have a JCSDA WG, should you? Workshop format
This year’s format, or the “old” one with most presentations in parallel sessions, or yet another model?
