Abstract

Abstract: The measurement of ocean optical parameters is an important part of ocean research. According to the transmission of the blue and green laser pulse, the lidar return signals were analyzed, and the vertical profiles of the lidar attenuation coefficient were studied with airborne polarization lidar. Simultaneously, the absorption coefficient and extinction coefficient of South China Sea were measured using AC-S. Comparing the lidar and in situ measurements, we found that the lidar attenuation coefficient is between the absorption and extinction coefficient. The correlation analyses of lidar attenuation coefficient with absorption and extinction coefficient were carried out respectively, and it was shown that they have a good correlation. Overall, the results indicated that the airborne polarization lidar is an efficient way to detect the profiles of ocean and the combination of airborne lidar and in situ measurements provide comparable and complementary information about ocean optical parameters.
