Dual Quantum Cascade Laser System For Simultaneous Measurements of 13CH4 and CH3D Methan Isotopolgues
Methane is the second most important atmospheric greenhouse gas after CO2 yet its global sources and sinks are still inadequately characterized. Monitoring the isotopic composition of atmospheric methane is one of the most promising approaches to closing the methane budget. Detailed process studies of isotopic fractionation associated with methane sinks and sources are also crucial. For both purposes, a real time instrument that can measure multiple isotopologues of methane is required. There are no existing field deployable instruments for the sensitive, real time measurement of CH3D. There are also no instruments available with sufficient precision to monitor ambient atmospheric 13CH4 (excluding the Aerodyne Research, Inc. predecessor to the proposed instrument). Hence, there is a need for sensitive, measurements of both isotopologues
