Gas solubility (Henry's law air-water partitioning coefficients)
Description
Gas solubility (Henry's law air-water partitioning coefficients)
Usage
GasSolubility(compound, T, S)
Arguments
compound
e.g. "O2"
T
temperature in Celsius
S
salinity
Details
Applies polynomial fits to empirical data where available (O2,CO2,N2O etc), or where this data is not available, uses the synthesis of Henry's law constants and temperature dependencies along with the salinity relationship from Johnson (2010) which in turn uses Rolf Sander's collection of Henry's law constants
Where available, gas-specific polynomial fits following the model of Weiss 1970 (equation 4) should be used in preference to the Johnson/Sander scheme. This is particularly important for long-lived (i.e. close-to equilibrium) gases such as N2, O2, Ar, CO2 and N2O. For shorter lived / far from equilibrium gases the simpler scheme will generally to a good job.
Value
partitioning coefficient in moles/litre/atmosphere
