FOCCUS WP9 MS9.1 Applications prototype: ESC3 - 3.2.1 - Improve storm surge forecasts on the Atlantic French coast

General information: The outputs of the Tolosa-SW model are provided as proof of prototype development resulting from the Coastal Application 3.2.1 “Improve storm surge forecasts on the Atlantic French coast” (doi:10.5281/zenodo.17064233 for reference). This item consists of a figure, an example of the expected output of the final application, and a dataset containing the information used to plot the figure. Figure: The figure Tolosa_SW-GLO_correction_ext01092024.png shows the sea surface height calculated by the Tolosa-SW model used by the French national storm surge forecasting system, and corrected in post-processing by the outputs of the Copernicus Marine Service's GLO-ANFC system. More specifically, this correction is calculated using the terms of global average sea level change due to water mass budget (global_mean_mass_volume_variation), global average steric sea level change- (global_mean_steric_variation) and ocean dynamic sea level (sea_surface_height). The figure shows the result for September 1, 2024, at 00:00. Data description: The dataset in the file Tolosa_SW-ssh_unstruct_20240901.nc is generated using Python (by the xarray library, CF-1.8 compliant) and contains the following fields: sea surface seight (m) sea surface height corrected by GLO-ANFC (m) latitude/longitude (°) other information on the unstructured grid (complying with the UGRID convention).
