Paper Abstract

Here, we present the results of a mobile campaign undertaken in late October to early November of 2018 to survey heterogeneity of the spatial distribution of CO2 and CH4 concentrations across West Siberia using the Picarro G4301 mobile gas concentration analyzer. The measurements were carried out along the following routes Tomsk–Karasevoe– Tomsk and Tomsk–Omsk–Tobolsk–Noyabrsk–Tobolsk–Chelyabinsk–Omsk–Tomsk. The highest baseline level of carbon dioxide mixing ratio of 431.0±2.2 ppm was observed at the western route segments between Chelyabinsk and Kurgan, and the lowest ones at segments Tomsk – Karasevoye, Demyanskoe – Noyabrsk, and Tobolsk – Yalutorovsk, where average concentrations of CO2 were 410.1±1.1 ppm, 410.7±1.6 ppm, and 411.5±1.5 ppm, respectively. Enhanced methane background (> 2000 ppb) was recorded in the oil and gas production areas, as well as in the vicinity of such large industrial centers as Kurgan and Chelyabinsk.
