gsw_pt_from_entropy

potential temperature with a reference sea 
pressure of zero dbar as a function of entropy

Contents

USAGE:

pt = gsw_pt_from_entropy(SA,entropy)

DESCRIPTION:

Calculates potential temperature with reference pressure pr = 0 dbar and
with entropy as an input variable.

potential temperature from entropy.

INPUT:

SA       =   Absolute Salinity                                  [ g/kg ]
entropy  =   specific entropy                                  [ deg C ]
SA & entropy need to have the same dimensions.

OUTPUT:

pt   =  potential temperature                                  [ deg C ]
        with reference sea pressure (pr) = 0 dbar.  
Note. The reference sea pressure of the output, pt, is zero dbar.

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
entropy = [400.3892; 395.4378; 319.8668; 146.7910; 98.6471; 62.7919;]
pt = gsw_pt_from_entropy(SA,entropy)
pt =
