Paper abstract bibtex The IBI 3D hourly solution was tested as an alternative initial and open boundary condition to the present methodology used by Hidromod based in the CMEMS global forecast. The tests were done for an implementation of the MOHID model to the Algarve coast with a ~400 m horizontal resolution. Models results were compared with several observation data sources: Lagos tidal gauge, Faro buoy temperature, Algarve-Huelva HF radar for December 2017. The tests lead to the follow conclusions: (1) downscaling of IBI solution for domains restricted to the continental shelf area do not present any numerical limitations; (2) for domains where a significant percentage of the model domain is located outside of the continental shelf, there is the need of follow the same downscaling methodology used in the IBI solution. In this methodology extra salinity and temperature (spectral nudging) sinks/sources terms are added to force the density field to converge outside of the shelf to the CMEMS global solution.
