WERA NorthernRadar

WERA

WERA NorthernRadar is an Oceanographic HF Radar providing simultaneous measurement of:

  • Surface currents maps
  • Ocean waves parameters and maps
  • Wind direction (wind speed under development)
These measured data are available
  • Over long distances (more than 200 km) and large areas with good temporal resolution (complete data set within less than 10 minutes)
  • with high spatial resolution (down to 250 m)

Principals of Operation
The WERA system (WavE RAdar) is a shore based remote sensing system using the over the horizon radar technology to monitor ocean surface currents, waves and wind direction (Gurgel, 1999). This long range, high resolution monitoring system operates with radio frequencies between 4 and 50 MHz. A vertical polarized electromagnetic wave is coupled to the conductive ocean surface and follows the curvature of the earth.

Applications
WERA NorthernRadar provide a lot of useful data for various applications. Typical users are:
  • meteorological institutes
  • coastal management (erosion, flooding, pollution, etc.)
  • port authorities & harbour management
  • environmental monitoring & research
  • oil & gas industries
  • oceanographic researchers
  • vessel traffic services (ship tracking is under development)
  • renewable energy providers (wind farm planning and management)
  • component for tsunami warning systems

The robust shore based system delivers reliable data even under extreme weather and dynamic ocean current conditions. This surface current image was taken during the passage of tropical storm Henri on the 5th of September 2003
