Experimental studies of trace gases in the atmosphere of arid and semi-arid territories of Mongolia.
Results of experimental studies of diurnal variability of the ground ozone, CO<sub>2</sub> and nitrogen oxides in the atmosphere of arid and semi-arid territories of Mongolia, obtained in researching expeditions of 2005 and 2006, are presented. Factors, leading to increased concentrations of trace gas admixtures, their connection with meteorological and turbulent characteristics of the atmosphere are under analysis.
