The IOOS Data Assembly Center (DAC) operates 24/7 to ensure comprehensive quality assurance and control for real-time observations. With swift reporting of station failures and data anomalies, the DAC supports data providers by identifying communication outages and degrading data within three hours. It assigns WMO identifiers to partners for real-time data release and maintains critical metadata. The DAC supports various stations, including NDBC buoys and coastal monitoring systems, contributing to coastal and oceanic data integrity.

Transcription de la présentation

  1. The IOOS Data Assembly Center Data Quality Control Effort

  2. IOOS DAC Capabilities • 24x7x365 service providing full-spectrum quality assurance and quality control of IOOS real-time observations.  • Report station failures to data providers within 3 hours of determination. • Detect real-time data anomalies via manual and automated quality control methods. • Report communication outages that impact data quality or the ability to deliver observations. • Report degraded data and contact provider within 3 hours to stop/correct the degraded data. • Assign all World Meteorological Observations (WMO) identifiers to partners so the data is released in real-time to the Global Telecommunication System (GTS). • Provide real-time QA/QC of Gulf of Mexico Oil and Gas platforms. • Maintain platform metadata in a data base for proper processing • Maintain National High Frequency Radar server and provide real-time observations via the server.

  3. NDBC Moored Buoys (1972-2007)

  4. Buoy Real-Time Data Availability 81.2%

  5. Station Growth (1999-2008)(nb. 8% growth June-December 2008)

  6. Number of IOOS Partner Stations Reporting

  7. DAC IOOS Support – FY08

  8. Percent of Stations Reporting 93% 92% 76%

  9. NDBC and 180 GCOOS Stations • NDBC Buoy / CMAN – 25 Stations • NDBC DART buoys (Detection and Reporting of Tsunamis) – 1 Station • NERRS (National Estuary Research Reserve System) – 5 Stations • NOS (National Ocean Survey) – 41 Stations • CDIP (Coastal Data Information Program—Scripps) – 1 Station • Shell Oil – 2 Stations • COMPS (Coastal Ocean Monitoring and Prediction System) – 20 Stations • Dauphin Island Sea Lab – 3 Stations • University of Southern Mississippi – 1 Station • LUMCON (Louisiana Universities Marine Consortium) – 4 Stations • TCOON (Texas Coastal Ocean Observing Network) – 11 Stations • LSU WAVCIS (Louisiana Sate University Wave Current Surge) – 4 Stations • Mariner Energy – 1 Station • TABS (Texas Automated Buoy System) – 9 Stations • TCOON (Texas Coastal Ocean Observing Network) – 11 Stations • MMS (Mineral Management Service) Oil and Gas – 67 Stations • High Frequency Radar network server
