A Robust System for a Reliable Operational Service • Main achievements are: • 2) Special attention to any factor causing potential recurrent • incidents Plan of mitigation / correction measures Incident causes (since April 2011): MyOcean2 User training workshop. Exeter, July 2014.
A Robust System for a Reliable Operational Service • IBI is a quite robust system • But sensitive to issues in the computing environment & acqusition of external input forcings • From April 2014. Back-up capability: reduction of impacts on users due to incidents in NOM PC • > 97% of the days, daily IBI forecast bulletin served without delay or problems. • Incidents more frequent outside working days MyOcean2 User training workshop.

High-Frequency IBI-REA performance on Spanish waters • High frequency IBI REA Validation with in-situ data from moorings (PdE PC) • Metrics computed using high frequency (1-h) in-situ measured data over the 10-yr period across 14 moorings from the Puertos del Estado Network. • Validation exercise performed with independent (in the sense of non-assimilated in the IBI-REA system) in-situ observational data. • Quite valuable to evaluate the skill of the IBI-REA system
