WebChromophoric Dissolved Organic Matter or Colored Dissolved Organic Matter (CDOM): Both refer to organic matter in water that absorbs strongly in the ultraviolet (UV) spectrum. Fluorescent Dissolved Organic Matter (fDOM) refers to the fraction of CDOM that fluoresces. fDOM is a surrogate for CDOM, and a fast and easy means of tracking DOM in ...
