Tunable laser induced scattering from coastal water

Abstract

This paper describes tunable laser-induced inelastic scattering measurements made on Chesapeake water. Results show both fluorescence and Raman signals were induced at laser wavelengths ranging from 180 to 530 nm. Depending on excitation laser wavelengths, Raman signals overlap with fluorescence signals at different spectral positions. At shorter excitation laser wavelengths, analyses of measurement data demonstrate that Raman signals can be recovered for water temperature retrievals. At longer excitation wavelengths, both fluorescence and Raman spectral shapes are corrupted. This paper describes the effects of superposed laser-induced signals on geophysical parameter retrievals through spectral analysis.
