olm.calcite.solutionFromCaPCO2

olm.calcite.solutionFromCaPCO2(Ca, PCO2, T_C=25.0, per_tol=0.001)

Creates a solution object from a given concentration of calcium and PCO2.

Parameters:

Ca : float, numpy.ndarray, or pandas Series

concentration of calcium in mol/L

PCO2 : float, numpy.ndarray, or pandas Series

partial pressure of CO2 (atm)

T_C : float, , numpy.ndarray, or pandas Series (optional)

temperature of solution in degrees Celsius (default = 25 C)

per_tol : float

the fractional change in H concentration between iterations upon which the iteration is terminated

Returns:

sol : solution object, numpy.ndarray of solution objects, or pandas Series of solution objects

Notes

Assumes a H20-CO2-CaCO3 system. Guesses concentration of H using relaxed charge balance assumption, and then iterates to full solution.
