Carbon Monoxide (CO) is measured in parts per billion (ppb).
Carbon Monoxide is measured via gas chromatograph and hot mercuric oxide detection.

Carbon Monoxide (CO) plays an important role in atmospheric chemistry.
Carbon Monoxide is highly variable in the atmosphere, meaning there are periods of increase and periods of decrease.
CO has an indirect greenhouse effect. Changes in CO affect the chemistry of the atmosphere, impacting the removal of Methane (CH4) and other radiative gases.
The NOAA ESRL GMD Carbon Cycle-Greenhouse Gases group (CCGG) conducts research to understand the global carbon cycle and its effects on climate. At CCGG measurements are made to determine baseline levels, trends and causes of variability of several atmospheric gases (carbon dioxide, methane and carbon monoxide), that have the potential to affect global climate.
To obtain detailed understanding of the short term as well as long term variations of the greenhouse gases, CCGG makes on-site measurements at the four NOAA/ESRL/GMD baseline observatories, which are far from any pollution sources affecting the gases of interest.
