Abstract:

Numerical Monte Carlo modelling of integrated fluorescence lidar returns in Case 1 marine waters was conducted. A dedicated program implementing coordinate recording of individual inelastic scattering events was developed to address these objectives. Modelled Raman scattering spectra and chlorophyll fluorescence intensities were obtained for three pigment concentrations and two probing wavelengths: 355 nm and 532 nm. Contributions to the integrated return signal from photons originating at different water depths and radial distances from the beam axis were quantified. For the first time, the spatial dimensions of the inelastic scattering signal formation volume were estimated. Results demonstrate that the signal is predominantly contributed by the region concentrated along the probing laser beam axis.
