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.
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 =
28.9930
27.9933
22.9945
9.9976
