Shipborne oceanic high-spectral-resolution lidar for accurate estimation of seawater depth-resolved optical properties.

ABSTRACT: Lidar techniques present a distinctive ability to resolve vertical structure of optical properties within the upper water column at both day- and night-time. However, accuracy challenges remain for existing lidar instruments due to the ill-posed nature of elastic backscatter lidar retrievals and multiple scattering. Here we demonstrate the high performance of, to the best of our knowledge, the first shipborne oceanic high-spectral-resolution lidar (HSRL) and illustrate a multiple scattering correction algorithm to rigorously address the above challenges in estimating the depth-resolved diffuse attenuation coefficient K_d and the particulate backscattering coefficient b_bp at 532 nm. HSRL data were collected during day- and night-time within the coastal areas of East Chi
