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
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
7
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
8
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 15 8 8 6 6 21
9
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
10
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
11
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
12
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 4
13
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
14
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
15
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 18 19 20
