A temperature calibration method for CDOM fluorescence LIF LiDAR
SPIE Proceedings, 2016The influence of temperature variations on the determined concentrations of dissolved organic matter (DOM) in water was investigated by laser induced fluorescence (LIF) technique in laboratory. The effect of temperature on CDOM fluorescence was investigated in freshwaters of Xixi River and in aqueous standards.

The carbon contained as dissolved organic matter (DOM) in the Earth’s oceans is an important factor in the global carbon cycle, but studying and tracking DOM in the aquatic environment can be challenging. However, the light-absorbing and emitting subcomponents of DOM, called chromophoric dissolved organic matter (CDOM) and fluorescent dissolved organic

Retrieval of hyperspectral CDOM absorption with integrating cavity sphere
2020<p>Typical measurements of the absorption coefficient of the chromophoric fraction of dissolved organic carbon (CDOM) are performed on filtered seawaters samples. Though samples could be stored in the dark at 4&#176; for up to 6 months, it is preferable to analyse them within 24 hours from collection as variation of ...

Photobleaching of chromophoric dissolved organic matter (CDOM) in rainwater
Journal of Atmospheric Chemistry, 2007Significant photodegradation of chromophoric dissolved organic matter (CDOM) in rainwater was observed after exposure to simulated sunlight. Fluorescence excitation emission spectra (EEMS) of precipitation revealed the presence of four major peaks all of which degraded upon photolysis with the greatest loss in the region characteristic of marine CDOM ...

CDOM distribution and CO2 production on the Southwest Florida Shelf
Marine Chemistry, 2004Abstract Partial pressures of carbon dioxide (pCO2) were measured in river and coastal waters on two cruises in November 1999 and June 2000 on the Southwest Florida Shelf. Supersaturation with respect to the atmosphere was observed for most river and near-shore waters in November 1999.

Hydrologic control and diurnal photobleaching of CDOM in a subarctic lake
Fundamental and Applied Limnology, 2001Changes in the concentration of chromophoric dissolved organic matter (CDOM) were determined over short (hours to days) and medium (weeks) time scales during summer in a shallow, polymictic lake in subarctic Quebec, Canada. CDOM fluorescence (F CDOM ) decreased linearly from mid-June until early August, consistent with the zero-order kinetics expected ...

[Construction and application of an onboard absorption analyzer device for CDOM].
Guang pu xue yu guang pu fen xi = Guang pu, 2014Colored dissolved organic matter (CDOM) plays an important role in marine ecosystems. In order to solve the current problems in measurement of CDOM absorption, an automated onboard analyzer based on liquid core waveguides (Teflon AF LWCC/LCW) was constructed.
