sw.alpha.over.beta {oce} | R Documentation |
Compute alpha/beta using McDougall's (1987) algorithm.
ab <- sw.alpha.over.beta(S, t, p, is.theta=FALSE);
S |
salinity [PSU] |
t |
Temperature or potential temperature [degC], according to is.theta |
p |
pressure [dbar] |
is.theta |
Set TRUE if t is theta or FALSE if t is in-situ |
McDougall (1987). Note the use of potential temperature, not temperature.
Value in psu/degC.
