Ruddick et al. [Appl. Opt. 39, 897 (2000)] extended the standard SeaWiFS atmospheric-correction algorithm for use over turbid coastal and inland waters. However, Ruddick’s method is based on the assumption of a spatially homogeneous constant ratio for the water-leaving reflectances normalized by the sun-sea atmospheric transmittance at 765 and 865 nm. Such first-order bb/a model-based assumption can result in an inaccuracy for highly turbid water. Using the first- and second-order bb/(a + bb) models as well as the second-order bb/a model (which, more realistically, do not assume spatial homogeneity ratio), we suggest using the modified assumption, R(8)−1 = α0R(7)−1 + (l1Q)−1 (1 − α0), instead of Ruddick’s assumption, in SeaWiFS atmospheric-correction algorithms for highly turbid waters.
