Abstract
We evaluated the performance of a recently developed absorption partitioning model [J. Geophys. Res. Oceans 120, 2601 (2015) [CrossRef] ] that derives the spectral absorption coefficients of non-algal particles, , and colored dissolved organic matter, , from the total absorption coefficient of seawater. The model’s performance was found unsatisfactory when the model was tested with a large dataset of absorption measurements from diverse open-ocean and coastal aquatic environments. To address these limitations, we developed a new model based on a different approach for estimating and from the sum of these two coefficients, , within the visible spectral region. The very good overall performance of the model is demonstrated, with no tendency for bias and relatively small absolute differences (the median ) between the model-derived and measured values of and over a wide range of aquatic environments.
