Abstract
Inversion of the total absorption () and backscattering coefficients of bulk water through a fusion of remote sensing reflectance () and Secchi disk depth () is developed. An application of such a system to a synthesized wide-range dataset shows a reduction of folds in the uncertainties of inverted (in a range of ) from 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 spectrum. With such a fusion, it is found that the uncertainty in the inverted total in the 350–560 nm range could be reduced to for the synthesized data, which can thus significantly improve the derivation of coefficients of other varying components. Although the inclusion of places an extra constraint in the inversion of , no apparent improvement over the quasi-analytical algorithm (QAA) was found when the fusion of and was applied to a field dataset, which calls for more accurate determination of the absorption coefficients from water samples.
