The Analysis of OCO-2 Satellite Measurements of CO2 in the Vicinity of Russian Cities


Spatiotemporal variability of CO2 has been analyzed on the basis of OCO-2 satellite measurements (more than 300 days during 4.5 years and more than 50 000 measurements) in the vicinity of Moscow, St. Petersburg, Yekaterinburg, Magnitogorsk, and Norilsk (circles with radii of 100 km from the city centers). The comparison of the measurements shows the XCO2 datasets with quality flag “0” to be homogeneous, amplitudes of XCO2 variations to be 5–6%, and standard deviations to be lower than 1%. The maximal spatial variations in XCO2 are 2–4%, which significantly differs from the analysis results for OCO-2 data with quality flag “1”.
