Mobile Condition

Abstract. Ethane can be used as a tracer gas to distinguish methane sources, both at the local and global scale. Currently, ethane can be successfully measured using flasks or dedicated in-situ analyzers. In our study, we consider the possibility of using the CRDS Picarro G2201-i instrument, dedicated to isotopic CH4 and CO2, for suitable measurements of ethane:methane ratio in mobile field, near-source conditions. Our work was divided into three steps. First, laboratory tests were run to characterize the instrument in stationary conditions. Then the instrument performance was tested in the field, as part of a controlled release experiment and finally during mobile measurements focused on gas compressor stations. The results from the field are compared with the results from other instruments, dedicated to ethane measurements. Our study clearly shows the potential of using the CRDS G2201-i instrument to determine the ethane:methane ratio in methane plumes in mobile condition with an ethane uncertainty of 50 ppb. Assuming typical ethane to methane ratio ranging between 0 and 0.1 ppb ppb−1 we conclude that the instrument can correctly estimate the “true” ethane to methane ratio within 1-sigma uncertainty in CH4 enhancements of 1 ppm or more as can be found in the vicinity of strongly emitting sites (such as natural gas compressor station).

Abstract. Detection and quantification of greenhouse-gas emissions is important for both compliance and environment conservation. However, despite several decades of active research, it remains predominantly an open problem, largely due to model errors and assumptions that appear at each stage of the inversion processing chain. In 2015, a controlled-release experiment headed by Geoscience Australia was carried out at the Ginninderra Controlled Release Facility, and a variety of instruments and methods were employed for quantifying the release rates of methane and carbon dioxide from a point source. This paper proposes a fully Bayesian approach to atmospheric tomography for inferring the methane emission rate of this point source using data collected during the experiment from both point- and path-sampling instruments. The Bayesian framework is designed to account for uncertainty in the parameterisations of measurements, the meteorological data, and the atmospheric model itself when performing inversion using Markov chain Monte Carlo (MCMC). We apply our framework to all instrument groups using measurements from two release-rate periods. We show that the inversion framework is robust to instrument type and meteorological conditions. From all the inversions we conducted across the different instrument groups and release-rate periods, our worst-case median emission rate estimate was within 36 % of the true emission rate. Further, in the worst case, the closest limit of the 95 % credible interval to the true emission rate was within 11 % of this true value.
