  7. Buoy Sensor Specifications

  8. Raw Data ORKAN Data Base & Log Data Base Automated Preprocessing (Range, spikes, etc.,) Visual Assessment (OCEAN INFO & ORIGIN) Comparison with climatological and previous years buoy data; Inter-database comparison; Comparison with data from Satellite, Ship, etc Flagging Quality Control Data Organising Formatting Store Dissemination to End Users Data Organising & Quality Controlled

  9. Quality Controlled Data Meteorological: Air Temperature Air Pressure Wind Speed & Direction Humidity Precipitation Short & Long Wave Radiations Oceanographic: Wave Height, Direction & Period (Spectrum) Current Speed and Direction Surface Temperature Salinity Water Quality: Dissolved Oxygen Chlorophyll-A Turbidity / Yellow Substance Hydrocarbon Radioactivity Data Products Single Parameter Distribution Joint Occurrence Table Time Series Plot Function Plot Progressive Vector Diagram Scatter Plot Rose Vector Diagram Data Report Analysis Extreme Value Analysis (Weibull & Gumbel) Harmonic Analysis Spectral Analysis (Waves) Extrapolation and Interpolation of Data Data Outputs of NDBP

  10. Regular users of NDBP data

  11. First fully indigenised buoy deployed off Ennore Port limits on 31st December 2002 deployed off Ennore Port on 31st Dec 2002

  12. Classification of Buoys • Environmental Buoys (EB) • Port Buoys (PB) • Ocean Buoys (OB) • Met Buoys (MB)
