Lidar has the capability to measure seawater vertical optical properties efficiently both day-time and night-time, though accurate retrieval is still challenging due to multiple scattering. Herein, we propose a Multiple scAttering correcTion and rEtrieval (MATE) algorithm suitable for shipborne, airborne and spaceborne lidars. The MATE algorithm provides the synchronous depth-resolved absorption, backscattering and diffuse attenuation coefficients of seawater. A good consistency was obtained between retrieved results and the data with a root mean square relative difference (RSMRD) of 6.36% for diffuse attenuation coefficient, corresponding to an improvement of 2 times over methods that neglect multiple scattering. These results indicate that the MATE algorithm has valuable application potential in the quantitative evaluation of marine biological parameters.

这是 MATE：用于精确激光雷达分析海水光学特性的多重散射校正检索算法

激光雷达能够在白天和夜间有效测量海水垂直光学特性，但由于多重散射，准确检索仍然具有挑战性。在此，我们提出了一种适用于船载、机载和星载激光雷达的多重散射校正和检索（MATE）算法。 MATE算法提供海水的同步深度分辨吸收、后向散射和漫衰减系数。反演结果与数据一致，漫衰减系数均方根相对差（RSMRD）为6.36%，比忽略多重散射的方法提高了2倍。这些结果表明MATE算法在海洋生物参数的定量评估中具有有价值的应用潜力。
