gsw_t_from_pt0

in-situ temperature from potential temperature with p_ref = 0 dbar

Contents

USAGE:

t = gsw_t_from_pt0(SA,pt0,p)

DESCRIPTION:

Calculates in-situ temperature from potential temperature with a 
reference pressure of 0 dbar of seawater.
It is also possible to calculate in-situ temperature from potential
temparature using the function gsw_pt_from_t.  In this case it would be
called with Absolute Salinity, SA, potential temperature referenced to
0 dbar, pt0, and the in-situ pressure (i.e. gsw_pt_from_t(SA,pt0,0,p)).

in-situ temperature from potential temperature.

INPUT:

SA  =  Absolute Salinity                                        [ g/kg ]
pt0 =  potential temperature                                   [ deg C ]
       with reference sea pressure (pr) = 0 dbar.
Note. The reference sea pressure of the output, pt0, is zero dbar.
p   =  sea pressure                                             [ dbar ]
       ( i.e. absolute pressure - 10.1325 dbar )
SA & pt0 need to have the same dimensions.
p may have dimensions 1x1 or Mx1 or 1xN or MxN, where SA and pt0 are MxN.

OUTPUT:

t   =  in-situ temperature (ITS-90)                            [ deg C ]

EXAMPLE:

SA = [34.7118; 34.8915; 35.0256; 34.8472; 34.7366; 34.7324;]
pt0 = [28.8099; 28.4392; 22.7862; 10.2262;  6.8272;  4.3236;]
p =  [     10;      50;     125;     250;     600;    1000;]
t = gsw_t_from_pt0(SA,pt0,p)
t =
  28.812304839034994
  28.451122322781689
  22.811570627670207
