The system operated at two sites, one near Colwyn Bay and the other near Formby Point, giving maximum coverage for resolving currents and wave conditions. The maximum range of the radar was around 100km with a resolution of 2km for sea surface currents and 5km for 2-D wave spectra.
Results from the radar will be compared with POL's pre-operational models of the Irish Sea and Liverpool Bay.
The radar was first deployed in March 2004 and as the system developed, real-time data was available on this website. The radar system was switched off 5th and 6th December 2011 at Formby/Llanddulas respectively, signalling the end of this set of measurements. Some plots are still available to view on this website, and also raw data. Quality controlled data will become available later.

It uses the shortest range and lowest power settings and is capable of imaging sea clutter (waves) to a distance of 5km and hard targets (e.g., ships) to a distance of 20km. This will give coverage across the lower Dee Estuary and into Liverpool Bay.
A WAMOS-II recording system will be installed to record the radar images with a resolution of 5m-10m. The WAMOS software will generate average 2D-wave spectra and surface currents, while POL software will provide water depth maps at regular intervals based upon the wave behaviour.
Water depth maps will show up bathymetric changes (i.e. sand movements, sand-bank movements) over short and long time scales. Additionally, a web camera records pictures of sea conditions and beach/sand-bank structures to supplement the radar data.
Hilbre Island Radar has been temporarily switched off (Jan2012)
However, another Radar is currently being operated at the following site:
Falls of Warness (Island of Eday, Orkney)
