mpas_tools.ocean.coastline_alteration.add_land_locked_cells_to_mask(dsMask, dsMesh, latitude_threshold=43.0, nSweeps=10)[source]

Find ocean cells that are land-locked, and alter the cell mask so that they are counted as land cells.

Parameters:
  • dsMask (xarray.Dataset) – A land-mask data set

  • dsMesh (xarray.Dataset) – MPAS Mesh data set

  • latitude_threshold (float, optional) – Minimum latitude, in degrees, for transect widening

  • nSweeps (int, optional) – Maximum number of sweeps to search for land-locked cells

Returns:

dsMask (xarray.Dataset) – A copy of the land-mask data set with land-locked cells added to the mask for the first region
