Variable: Sea surface salinity

Definition

Full name	Sea surface salinity
Definition	Salinity of sea water in the surface layer (upper ~ 1 m if observed in MW). In the open ocean the correct term should be “halinity” with reference of the diversity of salts involved.
Measuring Units	psu	Uncertainty Units	psu
Horizontal Res Units	km	Vertical Res Units
Stability Units	psu (Stability /decade)

Comment:	"Ocean surface salinity" renamed "Sea surface salinity" by analogy with "Sea surface temperature"
