EMPIRICAL EQUATION FOR THE INDEX OF REFRACTION OF SEAWATER

摘要

We 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. [References: 9]
