The article focuses on the use of cavity ring-down spectroscopy (CRDS) to obtain accurate measurements of carbon dioxide (CO2) and methane (CH4) greenhouse gases in the phase B campaign of Balanço Atmosférico Regional de Carbono na Amazônia in May 2009 in Brazil. It says that measuring the concentration of carbon dioxide is important in studying the carbon cycle and its role in global warming. Results show that CRDS offer more than 0.05 ppm accuracy.

    Methane (CH4) is an important greenhouse gas because it has 25 times the global warming potential of carbon dioxide (CO2) by mass over a century. Recent calculations suggest that atmospheric CH4 emissions have been responsible for approximately 20% of Earth's warming since pre-industrial times....

    Cavity ring-down spectrometers (CRDSs) have the capacity to make isotopic measurements of CO2 where concentrations range from atmospheric (~400 ppm) to 6000 ppm. Following field trials, it has come to light that the spectrographic lines used for CO2 have an interference with elevated (higher...
