A Regional Operational Model for the North East Atlantic: Model Configuration and Validation
An operational model for an area of the northeast Atlantic that encompasses all of Ireland’s territorial waters has been developed. The model is an implementation of the Regional Ocean Modelling System (ROMS) and uses operationally available atmospheric and boundary forcing, and a global tide soluti...

An operational model for an area of the northeast Atlantic that encompasses all of Ireland’s territorial waters has been developed.

It is run in an operational framework to produce 7-day hindcasts once a week, and daily 3-day forecasts which are published in a number of formats.
