ACRI-HE has developed an approach based on downscaling regional scale products along a stretch of coast suitable for user’s application. The downscaling procedure implies embedding a numerical model within the outputs of the Copernicus Marine environment monitoring Service (CMEMS), in order to simulate physical processes at a local scale.

The automated procedure has been implemented to generate high resolution figures according users’ requirements (the area of interest, physical variables and temporal scale).

It is based on a set of routines that enables the generation of a computational grid with a fine scale (a few hundreds of meters), the downloading of CMEMS outputs, the numerical simulation management and the post-processing of the numerical results (Figure 1). The numerical simulations are undertaken thanks to the finite elements hydro informatics TELEMAC suite (Hervouet, 2007[1]). It contains various modules dedicated to coastal free surface flows and offers the possibility to refine the spatial resolution by solving nonlinear equations on an unstructured grid using finite elements methods.

The downscaling procedure contains several steps beginning from area definition, coastline definition, grid generation and validation, CMEMS downloading and input data interpolation, model setting up, and simulation management, to results visualisation.

The small scale product is made available through SAFI interface.
