polaris.ocean.eos.compute_specvol

polaris.ocean.eos.compute_specvol(config: PolarisConfigParser, temperature: DataArray | float, salinity: DataArray | float, pressure: DataArray | float | None = None) → DataArray | float

Compute the specific volume of seawater based on the equation of state specified in the configuration.

Parameters:

• config (polaris.config.PolarisConfigParser) – Configuration object containing ocean parameters.

• temperature (float or xarray.DataArray) – Temperature (conservative, potential or in-situ) of the seawater.

• salinity (float or xarray.DataArray) – Salinity (practical or absolute) of the seawater.

• pressure (float or xarray.DataArray, optional) – Pressure (in-situ or reference) of the seawater.

Returns:

specvol (float or xarray.DataArray) – Computed specific volume (in-situ or reference) of the seawater.
