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

 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: 25_PODAAC_VALIDATED_AQUARIUS/SAC-D_DATA_SET_RELEASED Mission: Aquarius

 Jason-1 repositioned as geodetic mission as 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 Jason-1 and Grace

 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 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 GHRSST

 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 QuikSCAT

 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.) obs4MIPS and MEaSUREs

 New dataset acceptance policy driven by Dataset Gap Analysis  Annual review of proposed datasets (not mission mandated).  First review completed July Last in January  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 Community driven datasets 4 4

 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) Sea Ice and Ocean Color

 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 Ocean Wind and Topography

 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” SPURS Report
