1. NOAA IOOS SOS Implementations in 2008 Jeff de La Beaujardière, PhD NOAA IOOS Program DIF Sr Systems Architect

2. 2 Data Integration Framework (DIF) IOOS = Integrated Ocean Observing System DIF = First spiral of IOOS development Standardize on small number of services & encodings Implement at selected provider & customer sites Start with several core variables –Currents, Temperature, Salinity, Water Level, Winds, Waves, Ocean Color (chlorophyll) In situ data providers: –National Data Buoy Center (NDBC) –Center for Operational Oceanographic Products & Services (CO-OPS) Special considerations: –Point, Profile and Trajectory data –Platforms with multiple sensor types –Time-dependent metadata (Graphic by i3 Aerospace Technologies Pty Ltd – used with permission)

3. 3 Recommended Web Services and Data Encodings In-situ data (buoys, piers, ships) Gridded data (model outputs, satellite) OGC Sensor Observation Service (SOS) OpenDAP and/or OGC Web Coverage Service (WCS) XML based on OGC Observations and Measurements (O&M) NetCDF using Climate and Forecast (CF) conventions Images of data OGC Web Map Service (WMS) GeoTIFF, PNG etc. -possibly with standardized styles [*OGC = Open Geospatial Consortium] Data TypeWeb ServiceEncoding

4. 4 SOS GetObservation Result XML Encoding of In-Situ Data XML Extensible Markup Language Generic method for structuring text data OGC GML Geography Markup Language XML that can represent any geospatial feature OGC O&M Observations and Measurements Model GML that describes the act of measuring real-world phenomena and the result of the measurement specialized by IOOS DIF v0.6 schema Encoding convention for in situ data Schema and data record definitions for Point, Profile and Trajectory sampling features codified as

5. 5 Data Provider Status (expected by end of CY2008) Sensor Observation Service NDBC DAC - buoys, C-MAN, VOS, NOS NERRS, etc. IOOS DAC - Regional observations TAO DAC - Tropical Atmosphere Ocean DART DAC - Deep-Ocean Assessment and Reporting of Tsunamis National Water Level Observation Network PORTS® NDBC CO-OPS User Requests Sensor Observation Service High-Frequency Radar (HFR) surface currents Web Coverage Service & OPeNDAP Data Content & Encoding Standards Web Coverage Service & OPeNDAP Satellite Ocean Color (Aqua MODIS, Terra MODIS, SeaWiFS) CoastWatch Data Content & Encoding Standards Data Integrated from One Provider NDBC Data Assembly Centers (DACs) IOOS Variables: temperature, salinity, currents, water level, winds, waves, ocean color (chlorophyll)

6. 6 Conclusion Previously ad hoc mechanisms used by some NOAA data providers now replaced by standard approach Now undergoing testing to find & remove incompatibilities between NDBC & CO-OPS Assessment of improvement for data customers is planned for 2010 Would like to work with SWE community to develop and adopt “Ocean Observing Profile” of SOS In 2009 will revise & improve existing services, and add new service types (e.g., Catalog Service, WMS)
