Presentation Transcript

  1. Discovery and Web Services in Support of SST Datasets at the PO.DAAC Edward Armstrong, Jorge Vazquez Toshio M. Chin, Charles ThompsonJet Propulsion Laboratory/California Institute of Technology, Pasadena, CA Rosanna Sumagaysay-AoudaRaytheon, Pasadena, CANASA SST Meeting Nov. 2-4, 2011Courtyard Marriott, Miami, Florida

  2. Outline • Facet Search and Discovery • State of the Ocean • Dataminer • POET • THREDDS

  3. PO.DAAC dataset discovery

  4. Facet “drilling”

  5. State of the Ocean (SOTO) • Google Earth based web interface • Visualizations of near real-time parameters • SST (MODIS + blended) • SSTA • SSHA • chlorophyll (MODIS) • ocean winds (ASCAT) • Additional overlays • ocean storms from last 30 days • NDBC buoy data • Aquarius salinity • http://podaac-tools.jpl.nasa.gov/soto

  6. SOTO: SST + NDBC Buoy Data

  7. SOTO: SSTA + Recent Storms

  8. Dataminer • Level 2 swath subsetting web interface facilitating sub-granule queries based upon regional, temporal, and data summary constraints • Growing number of data products from PO.DAAC and other data centers • GHRSST MODIS Aqua and Terra * • GHRSST AMSR-E • Quikscat • Jason-2* • AIRS CO2* • http://podaac-tools.jpl.nasa.gov/dataminer

  9. Dataminer: Search Results

  10. Dataminer: Quicklook

  11. POET 2.0 • Level 3 & 4 subsetting web interface facilitating annotated imaging based upon product, spatial and temporal constraints • http://poet.jpl.nasa.gov • Customized outputs: • 14 possible formats • Multiple plot types (map, time series, animation, lon-time profile)

  12. POET 2.0: Selecting a Product

  13. POET 2.0: Request Result

  14. THREDDS Data Server (TDS) • Simplifies the discovery and use of scientific data. • Subsetting via OPeNDAP • Viewers via (Client Applications) • IDV (integrated data viewer), NetCDF Java Tools, Godiva2 • AGGREGATION • PO.DAAC TDS (SST Datasets) • MODIS AQUA L3 SST 4KM MONTHLY (4um/11um) (4km) • GHRSST L2P Gridded Global Subskin SST AMSRE (25km) • GHRSST L4 AVHRR_OI Global Blended SST Analysis (25km) • GHRSST L4 G1SST Global Foundation SST (1km) • GHRSST L4 MUR Global Foundation SST (1km)

  15. GHRSST/SST forum • Easy to use • One time registration (http://podaac.jpl.nasa.gov/forum/forum) • Maintains complete thread of all conversations on a particular topic

  16. Future Plans • Improved PO.DAAC Subsetter • Combines Dataminer and POET functionality into a single tool • Search, imaging, and subsetting for L2/L3/L4 data products • Revamped interface, efficient/fast search • Beta version to be unveiled at 2012 Ocean Sciences
