Remote Raman spectra for the monitoring of water column temperature

Lidar remote sensing is up to now the only technique capable of detecting water column temperature. This technique is based on the analysis of the water Raman spectrum. A significant improvement can be achieved with the introduction of high spectral resolution lidar systems. For this purpose, a method for water column temperature determination has been investigated in the laboratory in view of the lidar application. Moreover, field experiments have been carried out with a high spectral resolution fluorescence lidar
