An airborne lidar was used to study the smoke plume from the burning of a controlled oil spill on the ocean. The ratio of the amount of light (at a wavelength, λ, of 0.532 u.m) backscattered by the smoke to the amount of light extinguished by the smoke was determined by measuring the strength of a laser beam after it had passed through the smoke plume, been reflected from the ocean, and passed through the smoke plume again, and comparing this to the strength of the laser beam reflected directly from the ocean. The optical depth of the smoke (at λ = 0.532 µm) was typically between 0.2 and 0.5. The mass fluxes of smoke particles that passed through four vertical cross sections of the (nonsteady state) smoke plume were estimated from lidar measurements to be 142, 175, 423, and 414 g , compared to an average smoke mass production rate of ~770 g s. The spatial distribution of smoke mass along the long axis of the plume was also estimated from the lidar measurements; derived smoke mass concentrations were generally <300 µg , with a few isolated values up to ~800 µg .
利用机载激光雷达研究海洋上可控石油泄漏燃烧产生的烟羽。通过测量激光束穿过烟羽、从海洋反射并再次穿过烟羽后的强度，并将其与直接从海洋反射的激光束强度进行比较，确定了烟对光（波长λ为0.532微米）的后向散射量与烟熄灭的光量之比。烟的光学深度（λ = 0.532微米）通常在0.2至0.5之间。根据激光雷达测量，穿过（非稳态）烟羽四个垂直横截面的烟颗粒质量通量估计为142、175、423和414克，而烟的平均质量产生率约为770克/秒。还根据激光雷达测量估计了沿烟羽长轴的烟质量空间分布；得出的烟质量浓度一般<300微克/立方米，有几个孤立值高达约800微克/立方米。
