  4. 2012 UWG Recommendations for Data Stewardship CLOSED Recommendation 4: Annual dataset gap analysis and prioritization Recommendation 8: Work with GHRSST on metadata practices Recommendation 9: Dialog with the NOAA Unified Access Framework Group Recommendation 14: GHRSST guidance on L4 products Recommendation 15: GHRSST guidance on new GHRSST datasets Recommendation 21: HR-DDS telecom Recommendation 30-31: Emphasize NSIDC (OBPG) as the official cryosphere (ocean color) DAAC Recommendation 32: Removal of GHRSST ancillary ocean color dataset Recommendation 33: Accessibility of ocean color data by PO.DAAC tools and services OPEN Recommendation 6: Create public webpage that documents PO.DAAC’s best practices Recommendation 18: Review strategies/implementations followed for in situ data management Recommendation 19: Work with NASA HQ to establish/enforce standards for field campaigns Recommendation 20: Work with NODC to promote netCDF data templates for field campaigns

  5. Outline • Purpose • Present on new datasets, parameters, missions and best practices • Presentation Outline • Mission driven datasets • Aquarius, Jason, GHRSST, QuikSCAT, obs4MIPS, MEaSUREs • Community driven datasets • From Dataset Gap Analysis studies in the parameter focus areas of Ocean Temperature, Ocean Topography, Ocean Wind, Gravity, Salinity, Ocean Circulation • Also new synergistic parameters of Sea Ice, and Ocean Color • SPURS report

  6. Mission: Aquarius • Public Aquarius version 2 released Feb 2012 • Total 12 dataset versions released during the past year by the project (>250 datasets) and the JPL PI-provided CAP dataset • Advising OBPG on implementation of Climate Forecast metadata attributes • Support periodic ingest of other Aquarius Cal/Val datasets: MWR, WWAV, Ancillary-HYCOM • 954 registered users • Announcement: http://podaac.jpl.nasa.gov/announcements/2013-02-25_PODAAC_VALIDATED_AQUARIUS/SAC-D_DATA_SET_RELEASED

  7. Jason-1 and Grace • Jason-1 repositioned as geodetic missionas a result of new orbit • Jason-1 in safehold since 28 Feb • Jason-1 netCDF reformatted by project to correct inconsistencies • GRACE reprocessed to version 5 • Improved gravity model, tide model, atmospheric and ocean dealiasing

  8. GHRSST 6 14 15 8 21 • Met with GHRSST representatives P. Minnett (GHRSST chair), G . Cortlett (Project Office), C. Gentemann (MISST PI) • Discussed issues on policies for new GHRSST datasets, and metadata and documentation improvements • HR-DDS like system will be proposed through a European ESA call • PO.DAAC is continuing to support evolution and extension of ISO and Climate Forecast metadata standards for GHRSST and NASA

  9. GHRSST • Preparation ongoing for version 2 datasets from GHRSST • Currently testing ingest of revised L4 and L3 datasets, and VIIRS L2P (global 1 km) • GOES-15 and Windsat SST version 1 released • AATSR sensor on Envisat no longer operating

  10. QuikSCAT • Implemented JPL QuikSCAT L2B version 3 dataset • Version 3 is in Preview, awaiting full release (coming soon!) • QuikSCAT briefly came back to life for one week in Jan 2013 • Another reboot by the QuikSCAT Project is under consideration

  11. obs4MIPS and MEaSUREs • obs4MIPS • Global monthly 1 degree gridded satellite observation for CMIP5 model inter-comparisons • AMSRE SST, AVISO Absolute Dynamic Height, QS wind • MEaSUREs • Reprocessed (or additions) to MUR SST (Chin, JPL), CCMP winds (Atlas, AOML), Integrated SSHA (Ray, GSFC), Tellus (Zlotnicki, JPL) • PO.DAAC will archive and distribute future 2012 MEaSUREs selections: • New datasets for Sea Level (Willis, JPL), Gravity (Landerer, JPL) and pre-SWOT(Lettenmaier, Univ. of Wash.)

  12. Community driven datasets 4 • New dataset acceptance policy driven by Dataset Gap Analysis • Annual review of proposed datasets (not mission mandated). • First review completed July 2012. Last in January 2013. • 30-40 datasets have been identified as Tier 1 priority • Five new datasets have been acquired via this policy • Includes new synergistic parameter areas of sea ice and ocean color

  13. Sea Ice and Ocean Color 30 31 32 33 • Acquired David Long’s QuikSCAT-Derived Multi-Year sea ice age classification • Fully archived • Acquired “remote” datasets for MODIS and SeaWiFS L3 ocean chlorophyll-a • Some PO.DAAC tools and services available • THREDDS, SOTO, LAS • No archiving or granule distribution • Users directed to NASA Ocean Biology Processing Group (OBPG)

  14. Ocean Wind and Topography • BYU/SCP Enhanced Resolution Level 3 Sigma-0 datasets from David Long • JPL Oceansat-2 L2B dataset • Existing MOU allows JPL/NASA access to the data for dataset development and distribution • CSEOF Reconstructed Sea Level

  15. SPURS Report 18 19 20 • E. Lindstrom has requested that SPURS in situ and other data be “packaged” for the research community • In response PO.DAAC will submit a proposal with F. Bingham (SPURS PI) to NASA ESDIS • A hierarchy of data services and commensurate funding will be proposed • Complete funding will provide full discovery, access, tools and archive services • Following the NASA/ESDIS defined policy on adoption of new “missions” or “campaigns”

  16. Prioritization Plan Flow Chart: NASA Process
