Controlled-release testing of the static chamber methodology for direct measurements of methane emissions

to related objects

Abstract - 1 - 1 - 1 + 14/- 14  % and that optimal chamber configurations (i.e., chamber shape, volume, and use of fans) can improve accuracy to below ± 5  %. We note that smaller chambers (≤ 20  L) performed better than larger-volume chambers (≥ 20  L), regardless of the chamber shape or use of fans. However, we found that the use of fans can substantially increase the accuracy of larger chambers, especially at higher methane mass flow rates (≥ 100  g h- 1). Overall, our findings can be used to engineer static chamber systems for future direct measurement campaigns targeting a wide range of sources, including landfills, sewerage utility holes, and oil and natural gas infrastructure.
