Calculate dissolved CO2 concentration in mol/kg

Source: R/calc_CO2_conc.R
calc_CO2_molKg.Rd

Converts a measured or modeled CO2 mole fraction to dissolved CO2 concentration using atmospheric pressure, water-column pressure, vapor pressure, and the Weiss (1974) CO2 solubility coefficient.

Usage

calc_CO2_molKg(
  CO2_ppm,
  temp_water,
  water_depth_m,
  atmo_press,
  press_units,
  salinity = 0,
  waterDepth_m = lifecycle::deprecated()
)

Arguments

CO2_ppm

Numeric vector. Mole fraction of CO2 in air in parts per million.

temp_water

Numeric vector. Water temperature in degrees Celsius.

water_depth_m

Numeric vector. Water depth above the sensor in meters.

atmo_press

Numeric vector. Atmospheric pressure at the water surface.

press_units

Character string giving the units of atmo_press. See convert_pressure() for accepted pressure units.

salinity

Numeric vector. Salinity in practical salinity units. Defaults to freshwater (0).

waterDepth_m

[Deprecated] Use water_depth_m instead.

Value

Numeric vector of dissolved CO2 concentration in mol/kg.
