Data Management & Stewardship
Preserve NASA’s data for the benefit of future generations
Data AccessProvide intuitive services to
discover, select, extract and utilize data
Science Information Services
Provide a knowledgebase to help a broad user community understand and
interpret satellite ocean data and related information

OPENRecommendation 6: Create public webpage that documents PO.DAAC’s best practicesRecommendation 18: Review strategies/implementations followed for in situ data managementRecommendation 19: Work with NASA HQ to establish/enforce standards for field campaignsRecommendation 20: Work with NODC to promote netCDF data templates for field campaigns
2012 UWG Recommendations for Data Stewardship
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: http://podaac.jpl.nasa.gov/announcements/2013-02-
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
14 1586 21
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 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
Community driven datasets

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
30 31 32 33
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”
