  1. IOOS, NOAA and HF RadarQA/QC and Standards Jack Harlan National Ocean Service Center for Operational Oceanographic Products and Services QARTOD 2005 28 February 2005

  2. Current Activities within NOS • National Ocean Service - Center for Operational Oceanographic Products and Services (CO-OPS) • Developing QA/QC Methods • Developing Algorithmic Standards • Velocity Vector Products for Navigation • Tidal Velocity Products • Particle Trajectory Products • National HFR Data Server

  3. FY05 IOOS QA/QC and Standards • Level 1 Errors: Influence radial velocity • Spectral frequency estimation algorithms e.g. MUSIC • SNR • Level 2 Errors: Influence total velocity • E.g. Geometric Dilution of Precision (GDOP)  Algorithmic Standards

  4. Level 1 Error Analysis • Spectral Frequency Estimation <-> DOA • Codar SeaSonde uses MUSIC • NOAA Project • Effect of SNR • Averaged Spectra • Individual Frequency Bins • Empirical and Simulation-based

  5. Level 2 Error Analysis • Total Vector Formation • two-radial-only estimates (GDOP) • unweighted least-squares (LS) estimates • level-1 error-weighted LS estimates • single-site solutions • distance-weighted LS estimates • averaging radius-dependent LS estimates

  6. Future Work • Product Development • Trajectory-based • Assimilation into circulation models • Level 3 error analysis
