Abstract

In this paper, we explore the performance of a bio-optical model used to estimate the water leaving radiance at 412nm and under what conditions this constraint can improve retrieval of water leaving radiances in the VIS and NIR channels. We first demonstrate that the bio-optical model performance is well modeled by Hydrolight simulations under coastal water conditions and is particularly suitable for coastal waters and that the 412nm estimator is well correlated to insitu measurements from SeaBASS. We then show that unlike prior uses, the bio-optical estimator can also be used not only to improve retrieval for absorbing aerosols but can be used to improve retrieval errors when regional aerosol models are not included. Furthermore, we explore the optimal a-posteri correction and show that the original n=6 coefficient used for aloft absorbing aerosols may need to be refined.
