Connemara Operational SWAN Wave Model
The Marine Institute has implemented a SWAN wave model for the greater Galway Bay area called the Connemara model. SWAN (Simulating Waves Nearshore) is a third-generation spectral wave model which was primarily developed for use in coastal regions. The Connemara wave model has a horizontal resolution of ca. 200 metres. It is forced by winds produced by the ECMWF high resolution forecast, and is nested within the Marine Institute's Irish_Shelf wave model
The model is run every day to produce a 6-day forecast and a 1-day hindcast, and output includes standard wave parameters such as significant wave height, mean wave period (Tm02), peak wave period, and mean wave direction. Forecast data and a limited amount of hindcast data is available from the Marine Institute’s Thredds and ERDDAP servers.
Hindcast data is archived and is available on request.
The Connemara wave model forecast is produced on a best endeavours basis and should not be used for safety-critical applications.
