摘要Inversion of the total absorption (a) and backscattering coefficients of bulk water through a fusion of remote sensing reflectance (R-rs) and Secchi disk depth (Z(SD)) is developed. An application of such a system to a synthesized wide-range dataset shows a reduction of similar to 3 folds in the uncertainties of inverted a(lambda)(in a range of similar to 0.01-6.8 m(-1)) from R-rs (lambda) for the 350-560 nm range. Such a fusion is further proposed to process concurrent active (ocean LiDAR) and passive (ocean-color) measurements, which can lead to nearly "exact" analytical inversion of an R-rs spectrum. With such a fusion, it is found that the uncertainty in the inverted total a in the 350-560 nm range could be reduced to 2% for the synthesized data, which can thus significantly improve the derivation of a coefficients of other varying components. Although the inclusion of Z(SD) places an extra constraint in the inversion of R-rs, no apparent improvement over the quasi-analytical algorithm (QAA) was found when the fusion of Z(SD) and R-rs was applied to a field dataset, which calls for more accurate determination of the absorption coefficients from water samples.
