Methane CH 4 ) is the second largest greenhouse gas in the world after CO 2 . CH 4 emissions contribute 16% of the world's greenhouse gases. Although global CH4 emissions are much lower than global carbon dioxide emissions, their global warming potential (GWP) over 100 years is 28-36 times greater than that of carbon dioxide. Using satellites to observe methane is an effective means. This paper is aimed at Hebei Province, using TROPOMI onboard Sentinel-5P. The main research content: 1). The concentration of XCH 4 in Hebei Province has obvious seasonal trend (autumn > winter > summer > spring). 2). Due to the existence of some stable emission sources in the southwest of Hebei Province, there are obvious anomalous areas of stable high value of methane in these areas.
