  1. Ocean Modeling and Data Analysis --- Charge --- Coordinate efforts and develop methods to exploit Aquarius SSS to study ocean variability and air-sea interactions using data analysis and ocean models Working Group Discussion 10:50-12:20 July 21, 2010 Seattle, Washington, USA

  3. Explore more effective ways of group communications • Current: Aquarius/SAC-D Information and Discussion Forum • http://aquarius.gsfc.nasa.gov/forum/aquarius/forum_show.pl • Limitations: still reply on emails • No documents (.doc, .ppt) • No images (.gif) • No group mailing/broadcasting • Explore, test and recommend other tools: Google Doc, Google Group…other ideas, please email Yi.Chao@jpl.nasa.gov

  4. Phase 1: Pre-launch, Now to April 2011 • Assigned Task: To identify, assess and recommend a near real-time data set for SSS (SST, surface vector wind, waves) to be used by the Aquarius simulator • The data need to have the following characteristics • Global • Accessible in a public domain • Available in near real-time operational (similar to IGDR SSH data with a latency no more than a week) • Reasonable performance comparing with the observational data available

  5. SSS from 1/12 deg HYCOM Web space: http://ourocean.jpl.nasa.gov/SSS/ (sandbox to assess data quality before recommending to Aquarius APDS at GSFC)

  6. Near-Term Tasks • How realistic is the HYCOM SSS? • How realistic are the NCEP wind, Reynolds SST and IFREMER waves? • If not, what should be considered as the alternative data sets (NOGAPS wind, OSTIA and G1SST SST, NCEP waves)? • Sub-groups will be formed with more focused discussions on assessments • Recommendation: The Aquarius ancillary data file should include the same variable from multiple data sources (like the altimeter community), unless there is agreement on the best choice

  7. In Orbit Checkout (IOC): Launch + 45 daysPost Launch Assessment Review (PLAR) • First…Aquarius… • First Aquarius SSS weekly map (L3a) • First SSS 7-10 days map merging Aquarius with Argo+drifter+ships+moorings (L3b) • First SSS 7-10 days map merging Aquarius with Argo+drifter+ships+moorings and SMOS (L3c) • First assimilated SSS maps from ??? models (L4) • Data analysis and model results from ALL • Plan to collect and “share” a 1-slide summary for all Aquarius PIs • Form focused groups to minimize duplication and facilitate collaborations • Model intercomparisons • SSS merging methods (in situ, Aquarius, SMOS) • Other…

  8. Phase 3: IOC + 6 monthsScience Team Meeting after launch • More Data analysis and model results from ALL • Special journal issues, conference presentations, publications/reports • PO.DAAC will collect all the salinity related papers, and track future papers related to Aquarius
