gsw_alpha_CT_exact

thermal expansion coefficient with respect to 
Conservative Temperature

Contents

USAGE:

alpha_CT_exact = gsw_alpha_CT_exact(SA,CT,p)

DESCRIPTION:

Calculates the thermal expansion coefficient of seawater with respect to
Conservative Temperature.
Note that this function uses the full Gibbs function.  There is an 
alternative to calling this function, namely gsw_alpha(SA,CT,p),
which uses the computationally efficient 48-term expression for density 
in terms of SA, CT and p (McDougall et al., 2011).

respect to Conservative Temperature.

INPUT:

SA  =  Absolute Salinity                                          [ g/kg ]
CT  =  Conservative Temperature (ITS-90)                         [ 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_CT_exact  =  thermal expansion coefficient                   [ 1/K ]
                   with respect to Conservative Temperature

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
CT = [28.7856; 28.4329; 22.8103; 10.2600;  6.8863;  4.4036;]
p =  [     10;      50;     125;     250;     600;    1000;]
alpha_CT_exact = gsw_alpha_CT_exact(SA,CT,p)
