FCO2v2

This function calculates the CO2 flux at the air-sea interface for a temperature range of -2 to 40°C.

This is the second version of a function, called FCO2v2, which calculates the CO2 flux at the air-sea interface. The first version was developed by Chapa Balcorta in 2015. This new version accounts for temperatures ranging from -2 to 40°C.

Syntax:

[F_CO2, dpCO2, KCO2] = FCO2v2(pCO2_water, xCO2_atm, SST, SSS, wind);

Input:

- pCO2_water: the pCO2 of seawater

- xCO2_atm: the pCO2 of the atmosphere

- SST: the sea surface temperature

- SSS: the sea surface salinity

- wind: the wind speed at 10 metres above the sea surface

Output:

- CO2 flux= F_CO2 in mmol m⁻² d⁻¹

- dpCO2 = the gradient of pCO2 between the water and the atmosphere

- KCO2= the solubility constant of CO2.
