Building a Portuguese Coastal Operational Modelling System

Henrique Coelho and Paulo Leitão - Hidromod

Guillaume Riflet, Angela Cânas, Rodrigo Fernandes and Ramiro Neves - Maretec

Goal – Downscale from coastal to local

Operational Products

• Support water quality monitorization (ex: waste water, eutrophication analysis, HAB’s);

• Oil Spills (Emergence Response Systems);

• Seal level (floods, coastal erosion);

Helping Monitorization

MERIS

Upwelling Index versus Nitrate in the discharge area of the Guia Outfall

Methodology

• Atmospheric fluxes (MM5);

• Large scale circulation (Mercator or HYCOM);

• Rivers run off (INAG – Real Time River Flow Data);

• Tides (Fes2004);

• Hydrodynamic and Biogeochemical processes (MOHID);

Downscalling results• Estremadura Promontory (Downscalling Mercator)• Algarve Coast (Downscalling HYCOM)

Cadiz Golf

Validation – Satelite versus MOHID

• Sea Surface Temperature;

• Chlorophyll;• Altimetry;

Future Development

• Data assimilation : Optimal Interpolation and Kalman Filter;

• Interpolation and Extrapolation : Convolution methods (Higdon, 1998) ;

• Paralelization : Linux cluster;

Institutional Interaction

• MeteoGalicia (Atmospheric fluxes, Oil Spills);

• IntecMar (HAB’s, Oil spills);

• IPIMAR (HAB’s);

• ESEOO (Iberian strategy);

• Mercator (Large scale circulation);

• IBRIOOS (Task team of EUROGOOS for the Arc Atlantic);

Projects

• EROCIPS – Oil spills (underway);

• INSEA – Eutrophycation indexes (to during 2005);

• ECOOP – Sea level and HAB’s (to start in 2007);

• DYNCOSTAL – HAB’s
