Time Resolved Lidar Measurements on an Artificial Water Column

This paper presents remote measurements performed on an artificial water column with a fully timeresolved LIDAR technique, The results are analyzed in view of the possibility of evaluating the attenuation coefficient from the temporal dependence of the various signals (backscattering, water Raman diffusion and Dissolved Organic Matter fluorescence). This is done on the basis of a simple model which completely neglects the multiple scattering, justified by the narrow beam - narrow field of view configuration of the instrument. The measurements were performed on waters containing increasing concentrations of organic matter and the attenuation coefficient was used to extend the Raman normalization to a wide range of wavelength.
