Interpretation of Spectral LiDAR Backscattering off the Florida Coast

Blog Article

A multispectral backscattering LiDAR (Light detection and range) system (hereafter Oculus) was integrated into a wave glider and used to estimate the scattering order (i.e., single vs multiple collisions) of LIDAR backscattering, the water inherent optical properties (IOPs), the biogeo-chemical characteristics of particulate scatterers (i.e.

, relative size, composition) and their Electric Skillet motion) on shelf waters of South East Florida.Oculus has a dual-wavelength configuration (473 and 532 nm) and two detection geometries (off- and on-axis).Characteristics of scatterers were investigated based on two complementary LiDAR-derived proxies (the Structural Dissimilarity Index and the spectral slope of LiDAR backscattering).In March 2017, field measurements showed a covariation between direct and diffuse backscattering contributions during morning hours and away from shore.

LiDAR attenuation coefficients explained up to 57% of IOPs variability.The Dining Chair analysis of LiDAR-derived proxies suggested higher turbidity and larger particulates near the coast.
