Three-population model of phytoplankton absorption deployed on Plymouth Marine Laboratory (PML) computer
This computation involved: Three-population model of phytoplankton absorption deployed on Plymouth Marine Laboratory (PML) computer. A team led by Robert Brewin at the Plymouth Marine Laboratory, UK, has developed a model that calculates the phytoplankton absorption coefficient at various wavelengths based on three-component populations of phytoplankton which can be linked to the three size classes of phytoplankton (picophytoplankton, nanophytoplankton, and microphytoplankton).

More Information (under review)
A main characteristic of the model is that all the parameters that describe it have biological or optical interpretation.
The three-population model performs better than the two-population model at retrieving total phytoplankton absorption.
Accounting for the contributions of picophytoplankton and nanophytoplankton, rather than the combination of both as in the two-population model, improved significantly the retrieval of phytoplankton absorption at low chlorophyll-a concentrations.
Class-dependent specific absorption of phytoplankton derived using the model compares well with previously published models.
