gsw_t90_from_t48

ITS-90 temperature from IPTS-48 temperature

Contents

USAGE:

t90 = gsw_t90_from_t48(t48)

DESCRIPTION:

Converts IPTS-48 temperature to International Temperature Scale 1990
(ITS-90) temperature. This conversion should be applied to all in-situ
data collected prior to 31/12/1967.

ITS-90 temperature from IPTS-48 temperature.

INPUT:

t48   =  in-situ temperature  (IPTS-48)                        [ deg C ]

OUTPUT:

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

EXAMPLE:

t48 = [ 29; 28; 23; 10; 7; 4;]
t90 = gsw_t90_from_t48(t48)
t90 =
