gsw_t90_from_t68

ITS-90 temperature from IPTS-68 temperature

Contents

USAGE:

t90 = gsw_t90_from_t68(t68)

DESCRIPTION:

Converts IPTS-68 temperature to International Temperature Scale 1990
(ITS-90) temperature.  This conversion should be applied to all in-situ
data collected between 1/1/1968 and 31/12/1989.

ITS-90 temperature from IPTS-68 temperature.

INPUT:

t68   =   in-situ temperature  (IPTS-68)                       [ deg C ]

OUTPUT:

t90   =   in-situ temperature  (ITS-90)                        [ deg C ]

EXAMPLE:

t68 = [ 29; 28; 23; 10; 7; 4;]
t90 = gsw_t90_from_t68(t68)
t90 =
