UWG 2013 MeetingPO.DAAC Data Stewardship Status

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

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

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

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

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”
