Regardless of the radar system (WERA or SeaSonde), the primary product is the radial component of the sea surface current along a line between the radar station and a point on the sea surface. By combining radials measured at two stations surface current vectors can be constructed. These surface current vectors can then be used to study tides, wind-driven currents and perform lagrangian particle tracking. Raw data collected at each radar site are re-processed by the facility in order to assign quality control flags to data points. This is not possible in real-time because real-time data are produced by proprietary manufacturer software without quality control flags and it is not feasible to transfer the raw data to the facility in real-time. Each radial file contains a set of standard metadata fields, such as radar system type, operating frequency and bandwidth. Other metadata fields describe radar system type-specific parameters. Radial file metadata fields are described in a separate Ocean Radar data document. In addition, for WERA radar systems, the facility provides quality controlled heights of left and right bragg peaks, from which the wind direction can be inferred. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 Doppler Frequency Oceans | Coastal Processes | Coral Reefs Oceans | Ocean Circulation | Eddies Oceans | Ocean Circulation | Ocean Currents Oceans | Ocean Circulation | Upwelling Oceans | Ocean Circulation | Wind-driven Circulation Oceans | Ocean Waves | Significant Wave Height Oceans | Ocean Waves | Wave Frequency Oceans | Ocean Waves | Wave Length Oceans | Ocean Waves | Wave Period Oceans | Ocean Waves | Wave Spectra Oceans | Ocean Waves | Wave Speed/direction Oceans | Ocean Winds | Surface Winds Physical Oceanography Radial Surface Current SeaSonde (CODAR) HF Radar | Amplitude Direction Finding WERA HF Radar | Phased Array Website of the Integrated Marine Observing System (IMOS) documentDigital HTML Website of the Australian Ocean Data Network (AODN) documentDigital HTML Unnamed resource documentDigital License Graphic PNG Unnamed resource documentDigital HTML
