The Portuguese Coast Operational Modelling System (PCOMS) produce daily hydrodynamic results for the previous day and three days forecast for the Western Iberia Coast ran by the MARETEC team (Marine Environment and Technology Center http://www.maretec.org) at the Instituto Superior Técnico (http://www.ist.utl.pt). The obtained results would serve as ocean boundary conditions to different local models where a higher model resolution is needed, bringing ocean forecasts to more specific areas.
