SW_Psat Saturation (vapor) pressure of seawater
=========================================================================
USAGE: Pv = SW_Psat(T,S)
DESCRIPTION:
Vapor pressure of seawater given by [1] based on Raoult's law.
The pure water vapor pressure is given by [2]
INPUT: (all must have same dimensions)
T = temperature [degree C] (ITS-90)
S = salinity [g/kg] (reference-composition salinity)
OUTPUT:
Pv = vapor pressure [N/m^2]
VALIDITY: 0 < T < 200 C; 0 < S < 240 g/kg
ACCURACY: 0.1
