Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.
The NW Europe current model is a high resolution model providing hourly forecast data covering the portions of northwest europe. The Copernicus site refers to this model as: Atlantic - European North West Shelf.
The data is made available through the Copernicus service, in NetCDF format, and is converted into GRIB-2 data by LuckGrib.
The ocean physics analysis and forecast for the North-West European Shelf is produced using a forecasting ocean assimilation model, with tides, at 1.5 km horizontal resolution. The ocean model is NEMO (Nucleus for European Modelling of the Ocean), using the 3DVar NEMOVAR system to assimilate observations. These are surface temperature, vertical profiles of temperature and salinity, and along track satellite sea level anomaly data. The model is forced by lateral boundary conditions from the UK Met Office North Atlantic Ocean forecast model and by the CMEMS Baltic forecast product. The atmospheric forcing is given by the operational ECMWF Numerical Weather Prediction model. The river discharge is from a daily climatology. …

Of note, for the region covered by this model, is that the ocean depths vary a great deal. The image below is taken from the product user manual, cited above:
Note that the depths in the SW corner of the grid are much greater than the depths in the English Channel. The effect of the waters entering the channel and hitting this shelf can be seen in the GRIB data. A sample of this is shown below.
