X Quan, ES Fry
Applied optics, 1995•opg.optica.orgWe have determined an empirical equation for the index of refraction of water as a function
of temperature, salinity, and wavelength at atmospheric pressure. The experimental data
selected by Austin and Halikas [“The index of refraction of seawater,” SIO Ref. 76-1 (Scripps
Institution of Oceanography, La Jolla, Calif., 1976)] were fitted to power series in the
variables. A ten-parameter empirical equation that reproduces the original data to within its
experimental errors was obtained.
