1. Discovery and Web Services in Support of SST Datasets at the PO.DAAC Edward Armstrong, Jorge Vazquez Toshio M. Chin, Charles Thompson Jet Propulsion Laboratory/California Institute of Technology, Pasadena, CA Rosanna Sumagaysay-Aouda Raytheon, Pasadena, CA NASA SST Meeting Nov. 2-4, 2011 Courtyard 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
