Paper Abstract

In this study, a simulated-annealing algorithm is combined with well known semi-analytical model for deep water's inherent optical properties (IOPs) parameters. The IOPs is an important factor in considering and evaluating water type, subsurface light field, turbidity and pigment concentration. A simulated annealing (SA) algorithm is a global optimum process that could be applied for non-linear optimization problem in which multiparameter are present. In this work, four parameters are presented: Chl, ag440, S and bbp550. We evaluate our approach with self-computed data and IOCCG data set. The comparison between the retrieved results and the measured coefficients suggests that the differences are close to the accuracy limitations, and the two sets of results are in nice agreement, so the inversion results can be accepted.
