A Multicomponent Model of Chromophoric Dissolved Organic Matter Photobleaching¶§
Photochemistry and Photobiology, 2004ABSTRACTLight absorption by chromophoric dissolved organic matter (CDOM) plays a number of roles in natural waters, including both control of the underwater light field and the initiation of many photochemical reactions. A multicomponent analysis was used to describe the effects of UV and visible radiation on the optical absorption spectra of two ...

Inversion of Chromophoric Dissolved Organic Matter Using Sparse Regression
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Chromophoric dissolved organic matter (CDOM) retrieval remains to be a challenging task in water color remote sensing research due to its highly spatial and temporal variability. In this paper, we present a novel CDOM retrieval algorithm that takes advantage of the sparse learning, which can simultaneously perform feature selection and parameter ...

Chemical characteristics of chromophoric dissolved organic matter in rainwater
Atmospheric Environment, 2009Abstract Proton nuclear magnetic resonance (1H-NMR), UV absorbance and excitation-emission matrix (EEM) fluorescence spectroscopy were used to define the chemical characteristics of chromophoric dissolved organic matter (CDOM) in whole and C18 extracted rainwater.

Contaminant-mediated photobleaching of wetland chromophoric dissolved organic matter
Environ. Sci.: Processes Impacts, 2014Organic contaminants in wetlands undergo indirect photodegradation in the presence of chromophoric dissolved organic matter (CDOM), and in turn can mediate the photobleaching of CDOM.

The Delivery of Chromophoric Dissolved Organic Matter to the Sea
2001Abstract : The long-term goal of this research is to better understand the biogeochemical cycling of dissolved organic matter (DOM) in coastal waters. Of particular interest is the fate of terrigenous and dissolved organic matter in coastal marine systems and its affects on ocean color.

The binding of Ca(2+) and Cu(2+) by dissolved organic matter (DOM) exemplified by Suwannee River Humic Acid (SRHA) was examined in this study. Metal-DOM interactions were quantified using linear and log-transformed DOM absorbance spectra acquired at varying pHs and total Ca(2+) and Cu(2+) concentrations. The binding of Cu(2+) by DOM was examined in the
