资源简介：
The present data were obtained by vehicle-based measurements of methane and ethane concentrations conducted in September to October 2023. A gas analyzer was installed on the vehicle to measure atmospheric concentrations of methane and ethane at 1 second intervals. Positions of the vehicle (coordinates) and wind speed/direction were also recorded. The measurement data were used to locate methane emissions and estimate areal emissions with methane source types categorized by ethane to methane enhancement ratios.
