of atmospheric composition in Russia

The photo on the left hand side shows the Antonov-II aircraft flying above an eddy flux measurement towver, that is used to measure the exchange of CO2 between the forest and the atmosphere. Every month one flight is perfomed over the Central Forest Biosphere State Reserve at Fyodorovskoye, Russia (56° 27’ N, 32° 55’ E, 250 m asl), about 170 km north-west of Tver. The Antonov-II aircraft is flying from 100m up to 3000m over the CFR State Reserve, where biospheric carbon flux is monitored as part of Carboeurope-IP program.
The Antonov-II aircraft is equipped with one infrared analyzer for in-situ CO2 measurements, and one flask sampling unit. The flasks are analyzed at LSCE for CO2, CH4, N2O, SF6, CO, H2 mixing ratios and CO2 isotopes (13C and 18O). The graph on the right hand side shows the vertical profiles of CO2 in four different month. The uptake of CO2 by the vegetation in summer and the release in winter is clearly visible, up to 3000 m height.
