The investigation of atmospheric conditions in the steppe, forest-steppe, and semi-desert zones of Kazakhstan is relevant, the observations of air pollution are carried out in all big settlements. Satellite data are most suitable for solving the problems of quantitative and qualitative assessment of propagation of atmospheric pollutants. The contamination of the atmosphere over large territories which depends on the natural and anthropogenic sources of emission of trace gases can be determined from space. The statistical analysis of ground-based data on the atmospheric concentration of carbon monoxide (CO) over the most polluted big industrial cities is performed. The CO content in the atmosphere over Kazakhstan is analyzed using MOPITT satellite IR radiometer data for the period of 2007–2017. The seasonal and long-term variability of the total CO is revealed. The CO maximum falls on March-April, the minimum is registered in July to October. The average CO content in the atmosphere over Kazakhstan has decreased by 4.7% in the recent decade.
