polaris.ocean.vertical.pstar_init.PStarInitStep.init_tracers

abstractmethod PStarInitStep.init_tracers(ds: Dataset) → tuple[DataArray, DataArray][source]

Initialize conservative temperature (CT) and absolute salinity (SA) at p-star layer midpoints for the current outer iteration.

Parameters:

ds (xarray.Dataset) – Current p-star dataset, including ZTildeMid, ZTildeInterface, PseudoThickness, cellMask, minLevelCell, and maxLevelCell.

Returns:

conservative_temperature (xarray.DataArray) – CT with dimensions (Time, nCells, nVertLevels).
absolute_salinity (xarray.DataArray) – SA with dimensions (Time, nCells, nVertLevels).
