Hoge, FE (2003). Validation of satellite-retrieved oceanic inherent optical properties: proposed two-color elastic backscatter lidar and retrieval theory. APPLIED OPTICS, 42(36), 7197-7201.

Recent radiative transfer models show that: (1) regardless of elastic lidar receiver field of view (FOV), at vanishing lidar depth the lidar-derived attenuation coefficient k(lidar) --> a, where a is the total absorption coefficient per meter of depth; and (2) for a wide FOV as the lidar sensing depth approaches some large value (depending on water type) k(lidar) --> K-d, where K-d is the diffuse attenuation for downwelling irradiance. As a result, it is shown that a time-resolved, dual-wavelength-laser, elastic-backscattering lidar can retrieve the three principal oceanic optical properties: (1) the absorption coefficient of phytoplankton a(ph), (2) the absorption coefficient of chromophoric dissolved organic matter (CDOM) a(CDOM), and (3) the nonwater total constituent backscattering coefficient b(bt). The lidar-retrieved a(ph), a(CDOM), and b(bt) inherent optical properties can be used to validate corresponding satellite-derived products such as those from terra moderate-resolution imaging spectroradiometer (MODIS), Aqua MODIS, Sea-viewing Wide Field-of-view Sensor, (SeaWiFS), and other ocean color sensors.
