polaris.ocean.eos.teos10.compute_specvol

polaris.ocean.eos.teos10.compute_specvol(sa: DataArray, ct: DataArray, p: DataArray) → DataArray[source]

Compute specific volume from co-located p, CT and SA.

Notes

  • This function converts inputs to NumPy arrays and calls

    gsw.specvol directly for performance. Inputs must fit in memory.

  • Any parallelization should be handled by the caller (e.g., splitting

    over outer dimensions and calling this function per chunk).

Parameters:

  • sa (xarray.DataArray) – Absolute Salinity at the same points as p and ct.

  • ct (xarray.DataArray) – Conservative Temperature at the same points as p and sa.

  • p (xarray.DataArray) – Sea pressure in Pascals (Pa) at the same points as ct and sa.

Returns:

xarray.DataArray – Specific volume with the same dims/coords as ct and sa (m^3/kg).
