Estimation of methane sources from concentration measurements in the area of gas production in the north of Western Siberia

摘要: Data on atmospheric methane concentrations, measured at different levels (20, 30, and 60 m) with a time step of 20 min an observation point distance 50 km from the Urengoi field, are presented. The NOAA HYSPLIT model was used to identify technogenic emissions, method nocturnal accumulation evaluate emissions wetlands. It is demonstrated that observed short-term increases in concentration can be caused by salvo gas during technological operations field. Mean flux density estimated for wetland adjoining point.
