Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestriaThe photochemical decomposition of the dissolved organic matter DOM can have a significant impact on the landscape-atmosphere carbon exchange. However, little is known about how changing characteristics of DOM due to water browning (allochthonous inputs of DOM from terrestrial sources) affect the photochemical processing of the DOM.
