gsw_valence_factor

Contents

USAGE:

valence_factor = gsw_valence_factor

DESCRIPTION:

This function returns the valence factor of sea salt of Reference 
Composition, 1.2452898.  This valence factor is exact, and follows from
the definition of the Reference-Composition Salinity Scale 2008 of
Millero et al. (2008).  The valence factor is the mole-weighted square
of the charges, Z, of the ions comprising Reference Composition sea salt.

OUTPUT:

valence_factor  =  valence factor of sea salt of Reference Composition
                                                             [ unitless ]

EXAMPLE:

valence_factor = gsw_valence_factor

valence_factor =

  1.2452898
