The features of the distribution of methane in the atmosphere of Kazakhstan are considered on the basis of space sensing data. At all seasonal distributions, a tendency is observed towards an increase in the methane content in Kazakhstan over the period under consideration. Generally, the content of methane decreases sharply higher the 100 hPa level (altitude about 16 km). The maximum content of methane is observed in July in the atmosphere in the region from 600 hPa to 200 hPa. According to the vertical distributions, the highest methane content is observed in the northeast of Kazakhstan, while the lowest in the south. According to 2016–2018 ground observations of Kazgidromet, the highest methane concentrations in the surface layer of the atmosphere are observed in the cities of Ust-Kamenogorsk, Ridder, Semey and Karaganda. East Kazakhstan, Karaganda and Pavlodar Regions are the territories with maximum methane content in the atmosphere. Turkestan Region is the region with the minimum content of methane in the atmosphere.
