| Abstract: | Data on the volume concentration of carbon oxide (CO) in surface-air samples taken in European Russia, which were obtained using the Fourier transform spectroscopy method, are given. Over 16 years of measurements, this concentration decreased by 28%. These measured concentrations of CO are separated into its regional natural background and anthropogenic components. Seasonal variations in the concentration of CO are separated from its background concentration. Their extreme intra-annual values and mean amplitudes are determined. An empirical model of time variations in the concentration of CO is proposed. The atmospheric concentration of the CO anthropogenic component decreased by ~61 ppb over the measurement period. |
