Abstract

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”.

俄罗斯城市附近OCO-2卫星对CO 2的测量分析

摘要

在莫斯科，圣彼得堡，叶卡捷琳堡，马格尼托哥尔斯克和诺里尔斯克（圆圈）附近，基于OCO-2卫星测量（4.5年内超过300天，超过4.5万次测量）对CO _2的时空变化进行了分析。距市中心100公里的半径）。测量结果的比较表明，质量标记为“ 0”的XCO ₂数据集是同质的，XCO _2的变化幅度为5–6％，标准偏差小于1％。XCO ₂的最大空间变化为2-4％，这与质量标记为“ 1”的OCO-2数据的分析结果明显不同。
