gsw_SAAR
Absolute Salinity Anomaly Ratio
Contents
USAGE:
SAAR = gsw_SAAR(p,long,lat)
DESCRIPTION:
Calculates the Absolute Salinity Anomaly Ratio.
INPUT:
p = sea pressure [ dbar ]
( i.e. absolute pressure - 10.1325 dbar )
long = longitude in decimal degrees [ 0 ... +360 ]
or [ -180 ... +180 ]
lat = latitude in decimal degrees north [ -90 ... +90 ]
p, long & lat need to have the same dimensions.
OUTPUT:
SAAR = Absolute Salinity Anomaly Ratio [ unitless ]
in_ocean = 0, if long and lat are a long way from the ocean
= 1, if long and lat are in the ocean
Note. This flag is only set when the observation is well and truly on
dry land; often the warning flag is not set until one is several
hundred kilometres inland from the coast.
EXAMPLE:
p = [ 10; 50; 125; 250; 600; 1000;]
lat = [ 4; 4; 4; 4; 4; 4;]
long = [ 188; 188; 188; 188; 188; 188;]
[SAAR, in_ocean] = gsw_SAAR(p,long,lat)
