Convert CO2 partial pressure to mole fraction — pCO2_to

Converts water-vapor-corrected CO2 partial pressure, pCO2, to CO2 mole fraction, xCO2.

Usage

pCO2_to_xCO2(temp_water, pCO2_uatm, atmo_press, press_units, ...)

Arguments

temp_water: Numeric vector. Water temperature in degrees Celsius.
pCO2_uatm: Numeric vector. Partial pressure of CO2 in microatmospheres.
atmo_press: Numeric vector. Atmospheric pressure.
press_units: Character string giving the units of atmo_press. See convert_pressure() for accepted pressure units.
...: Additional arguments passed to calc_vapor_press(), such as salinity or method.

Value

Numeric vector of CO2 mole fraction in parts per million.
