英文摘要: We present atmospheric CO2 and δ(O2/N2) from flask samples taken on board aircraft over Fyodorovskoye (56°27'N, 32°55'E) at heights of 3000m and 100m between 1998 and 2008. The long-term trends for CO2 and δ(O2/N2) are similar for both sampling heights, and also similar to observations from marine background station Mace Head (Ireland) and coastal station Lutjewad (the Netherlands). The seasonal CO2 amplitude at 100m was almost twice as large as at 3000m and a phase shift in the seasonality of about two weeks between both sampling heights was observed. This indicates a dominant influence on CO2 in the boundary layer from the regional biosphere which is confirmed by analysis of the δ(O2/N2) to CO2 oxidative ratio (OR). Together with simulations with the TM3 model, our data suggest that the observed OR of-1.7±0.2 in the free troposphere is mainly driven by exchange processes with the ocean. Within the boundary layer an OR of-0.89±0.12 was observed which supports the results of other recent studies suggesting the commonly used value of-1.1 for biospheric OR is likely too low. © 2014 Elsevier Ltd.
