polaris.ocean.eos.teos10.compute_specvol

polaris.ocean.eos.teos10.compute_specvol(sa: DataArray | float, ct: DataArray | float, p: DataArray | float) → DataArray | float

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

Notes

• For xarray inputs, 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 (float or xarray.DataArray) – Absolute Salinity at the same points as p and ct.

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

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

Returns:

float or xarray.DataArray – Specific volume with the same dims/coords as the input arrays (m^3/kg), or a scalar if all inputs are scalar.
