About:
Here, the atmospheric measurement and simulation data used in "Continuous CH4 and d13CH4 measurements in London demonstrate under-reported natural gas leakage" (Saboya et al., 2022) published in Atmospheric Chemistry and Physics is provided.
Atmospheric Measurements
Atmospheric measurements of methane (CH4), its carbon-13 isotopic tracer (d13CH4), wind direction and wind speed have been made from the top of the Huxley building at Imperial College London. The data presented here span from March 2018 to October 2020. Twenty-minute averaged atmospheric CH4 and d13CH4 measurements made using a Picarro G2201-i isotopic analyser are included, as processed by GCWerks software. These data are in the file "GRAVEN_LAB_MEASUREMENTS_FINAL".
Atmospheric simulations
Atmospheric simulations were created by combining global emissions (EDGAR v4.3.2) and UK national emissions (NAEI) of CH4 with back-trajectories produced in NAME at multiple spatial resolutions. Simulations of d13CH4 are based on a mass-balance approach.
For full-details about the atmospheric measurements and simulations see Saboya et al. (2022).
