Comparison of oceanic lidar experiments and simulation results

Oceanic lidar is a vital remote sensing device for detecting the upper ocean and constructing the 3-D ocean observation network. In this paper, the experimental data of lidar were compared with Monte Carlo(MC) simulation, analytical model and in situ data to find their matched-degree. Compared with experimental lidar signals, the MC simulation and analytical model have high agreement (R²>0.97). The normal lidar equation approximately adopting the in situ diffuse attenuation coefficient (K_d) also has good consistency (R²>0.92). The retrieved lidar attenuation coefficients show similar results. The MC simulation and the analytical model have better consistency. The results show that the experimental results of oceanic lidar match well with the simulation results of MC and analytical model.
