polaris.ocean.eos.convert_tracer_pair

polaris.ocean.eos.convert_tracer_pair(temperature: DataArray | ndarray | float, salinity: DataArray | ndarray | float, target: str, pressure: DataArray | float, lon: DataArray | ndarray | float, lat: DataArray | ndarray | float) → tuple[DataArray, DataArray]

Convert a single temperature and salinity pair to the target convention.

This is the array-level counterpart of convert_tracers(), for callers that have tracers in hand rather than in a dataset. See that function for the accuracy of pressure.

Parameters:

• temperature (float, numpy.ndarray or xarray.DataArray) – Conservative or potential temperature, according to the convention being converted from.

• salinity (float, numpy.ndarray or xarray.DataArray) – Absolute or practical salinity, at the same points as temperature.

• target ({'teos-10', 'mpas-ocean'}) – The tracer convention to convert to.

• pressure (float or xarray.DataArray) – Sea (gauge) pressure in Pa, broadcastable against the tracers.

• lon (float, numpy.ndarray or xarray.DataArray) – Longitude(s) in degrees, either a nominal scalar value (e.g. on a planar mesh) or an array with dimension nCells.

• lat (float, numpy.ndarray or xarray.DataArray) – Latitude(s) in degrees, a scalar or an array with dimension nCells, as for lon.

Returns:

• temperature (xarray.DataArray) – The temperature in the target convention.

• salinity (xarray.DataArray) – The salinity in the target convention.
