gsw_alpha_on_beta_CT_exact

thermal expansion divided by the saline 
contraction coefficient

Contents

USAGE:

alpha_on_beta_CT_exact = gsw_alpha_on_beta_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates alpha divided by beta, where alpha is the thermal expansion
coefficient and beta is the saline contraction coefficient of seawater 
from Absolute Salinity and Conservative Temperature.
Note that this function uses the full Gibbs function.  There is an 
alternative to calling this function, namely gsw_alpha_on_beta(SA,CT,p),
which uses the computationally efficient 75-term expression for specific
volume in terms of SA, CT and p (Roquet et al., 2015).

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
CT  =  Conservative Temperature                                [ deg C ]
p   =  sea pressure                                             [ dbar ]
       (ie. absolute pressure - 10.1325 dbar)
SA & CT need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA & CT are MxN.

OUTPUT:

alpha_on_beta_CT_exact  =  thermal expansion coefficient with respect
                           to Conservative Temperature divided by the 
                           saline contraction coefficient at constant 
                           Conservative Temperature.    [ kg g^-1 K^-1 ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
p =  [     10;      50;     125;     250;     600;    1000;]
alpha_on_beta_CT_exact = gsw_alpha_on_beta_CT_exact(SA,CT,p)
