Mobile measurements improve methane leak detection in gas distribution systems, highlighting the need for uniform emission quantification methods.
Key Points
Using the integrated spatial peak area improves consistency in methane emission estimates across measurement devices.
Controlled experiments in cities like London and Toronto evaluated various devices, revealing better results with the integrated spatial peak area metric.
A minimum of three transects and ideally five to seven is recommended for accurate emission quantification to aid in effective leak repair prioritization.
Variability was noted in measurements across the same release point, contributing to uncertainty in the emission quantification process.
