AMM12 Boundary Coordinates

The AMM12-BDY-analysis.ipynb Jupyter Notebook is an analysis of the differences in results obtained from runs of the AMM12 configuration with the unstructured boundaries (BDY) set via the 2 available mechanisms in NEMO-3.4:

  • using a coordinates.bdy.nc file (stock configuration)

  • using a nambdy_index namelist

That analysis lead to our decision to use boundary coordinate calculations driven by the nambdy_index namelist for Salish Sea NEMO.
