Available online 12 March 20114 摘要Despite the importance of CDOM to upper ocean biogeochemical processes and optics, our current understanding of its spatial and temporal distributions and the factors controlling these distributions is very limited. This eventually prevents an understandi

This work aims to present a new approach for accurate modeling of absorption spectra of CDOM (acdom and deriving information on its composition in global ocean waters. The modeling approach uses measurements (

The robustness of this model was rigorously tested on three independent datasets, such as NOMAD in situ data, NOMAD SeaWiFS match-ups data and IOCCG simula
