Short summary
We carried out a field study across eleven industrial sites of oil and natural gas production/processing in Southwest China, investigating the methane leakage pattern based on ground and airborne monitoring/sampling techniques. Based on a novel isotope method to trace methane sources, we identified that the methane emission from the oil and gas sites makes the major contribution to changes in atmospheric methane isotope signals.
