This dataset contains mobile measurements of ambient methane collected during a controlled release of methane. Methane was released from a stationary source while a vehicle repeatedly drove past the release point, transecting the resulting methane plume multiple times. The objective of the experiment was to evaluate the capability of mobile platforms to detect methane plumes and to examine the relationship between methane release rates (in L/min) and key plume metrics, such as the maximum measured mole fraction and the integrated methane enhancement during individual plume transects. The experiment was conducted on an airfield near Bedford from 13-14/05/2024.

The experiment was a collaboration between the National Physical Laboratory (NPL, United Kingdom) and the Royal Holloway University of London (RHUL).
