2012 uwg recommendations for data stewardship
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 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


Outline
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


Mission aquarius
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


Jason 1 and grace
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


Ghrsst

  • 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


Ghrsst1
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


Quikscat
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


Obs4mips and measures
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.)


Community driven datasets
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

  • 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)


Ocean wind and topography
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

  • 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”
