Computes vapor pressure of seawater (atm) from temperature and salinity
vapress(S=35, T=25, form="d2007")
S |
Salinity on the practical salinity scale, default is 35 |
T |
Temperature in degrees Celsius, default is 25oC |
form |
choose either "d2007" for the best-practices formulation to compute vapor pressure of seawater from Dickson et al. (2007) or "wp1980" for the formulation from weiss and Price (1980). |
Computes the vapor pressure of seawater pH20 following best practices (Dickson et al., 2007). That computed pH20 is identical, when rounded to the 4th decimal place, with that computed by the equation from Weiss and Price (1980).
