What is CDOM monitoring?

Our CDOM/FDOM sensor measures levels of UV light in water. A common use for an FDOM sensor is the continuous monitoring of wastewater discharge. The CDOM sensor is also used to assess the human influence on rivers and streams. Used in long term deployment, CDOM measurements can be used to identify trends.

What is CDOM chemistry?

Colored dissolved organic matter (CDOM) is the optically measurable component of dissolved organic matter in water. Waters containing high amounts of CDOM can range from brown, as in many rivers, to yellow and yellow-brown in coastal waters.

Why is CDOM important?

Along with turbidity and chlorophyll, CDOM is an important consideration for determining light attenuation in a water body. Light attenuation is the loss of light with depth and is commonly used to set minimum light requirements and maximum depth targets in determining sustainability and restoration goals.

What is chromophoric dissolved organic matter?

Chromophoric dissolved organic matter (CDOM) is the fraction of the dissolved organic carbon (DOC) pool that absorbs light in both the ultra violet and visible ranges (Kirk, 1994). There is a strong experimental basis for remote measurements of CDOM.

What does Cdom mean?

Cumulative Days on Market
Cumulative Days on Market (CDOM): The Cumulative Days on Market accumulates on each listing and takes into account previous listings of the same property.

What is Cdom vs Dom?

The What: DOM measures the number of days from the last time a listing is listed to the last pending status before the listing is sold. CDOM measures the number of days from when a property is first listed to when a property goes into the last pending status before being sold.

Does Cdom absorb nutrients?

Photochemical Processes CDOM is the principal light-absorbing component of the dissolved organic matter (DOM) pool in sea waters, far exceeding the contributions of discrete dissolved organic or inorganic light-absorbing compounds.

Why is organic matter dissolved?

Dissolved organic matter is an important component of the global carbon cycle and is among the most reactive pools of organic material at Earth’s surface. (Hedges 2002; Hansell and Carlson 2015). In marine systems , DOM is the primary currency of the microbial loop as it provides a food and energy source to microbes.

What is Dom vs Cdom?

What is Dom PDOM Cdom?

Days On Market (DOM) data has been available for buyers for quite a while now, with CDOM a more recent addition. CDOM (Cumulative Days On Market) includes days on market for not only the current listing, but also listings that were cancelled or expired only to be re-listed in a short time.

What is Cdom in water?

Chromophoric 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.

Is Dissolved Organic Carbon good or bad?

How Does Dissolved Organic Carbon Affect My Health? DOC can interfere with the effectiveness of disinfection processes such as chlorination, ultraviolet and ozone sterilization. DOC can also promote the growth of microorganisms by providing a food source.
