Journal ArticleDOI
Observations of atmospheric variability and soil exhalation rate of radon-222 at a Russian forest site Technical approach and deployment for boundary layer studies
Ingeborg Levin,Matthias Born,Matthias Cuntz,U. Langendörfer,Stefan Mantsch,Tobias Naegler,Martina Schmidt,Andrej Varlagin,Stefan Verclas,Dietmar Wagenbach +9 more
TL;DR: In this article, a monitor for continuous observations of the atmospheric 222 Rn daughter activity has been improved and successfully implemented in a field study in the European Taiga (Fyodorovskoye Forest Reserve).
Journal ArticleDOI
Three years of aircraft-based trace gas measurements over the Fyodorovskoye southern taiga forest, 300 km north-west of Moscow
M. Ramonet,P. Ciais,I. L. Nepomniachii,K. N. Sidorov,R. E. M. Neubert,U. Langendörfer,David Picard,V. Kazan,Sébastien C. Biraud,Mykola Gusti,Olaf Kolle,Ernst Detlef Schulze,Jon Lloyd +12 more
TL;DR: In this article, the authors used a linear regression analysis applied to flask measurements of CO, CH4 and δ 13 C versus CO2 in the free troposphere, which indicated that industrial emissions over Europe are a dominant source of synoptic variability in wintertime in air masses reaching Fyodorovskoye.
Journal ArticleDOI
Modelling of biospheric CO2 gross fluxes via oxygen isotopes in a spruce forest canopy: a 222Rn calibrated box model approach
U. Langendörfer,Matthias Cuntz,Philippe Ciais,Philippe Peylin,Thierry Bariac,Irena M. Milyukova,Olaf Kolle,Tobias Naegler,Ingeborg Levin +8 more
TL;DR: One-dimensional box model estimates of biospheric CO2 gross fluxes are presented in this article, based on a set of measurements performed during the EUROSIBERIAN CARBONFLUX intensive campaign between 27 July and 1 August 1999 in a natural Picea abies forest in Russia.
Journal ArticleDOI
Seasonal variability of greenhouse gases in the lower troposphere above the eastern European taiga (Syktyvkar, Russia)
K. N. Sidorov,A. Sogachev,U. Langendörfer,Jon Lloyd,I. L. Nepomniachii,N. N. Vygodskaya,Martina Schmidt,Ingeborg Levin +7 more
TL;DR: In this article, a three year long record of regular vertical aircraft profiling for continuous atmospheric CO2 mixing ratio measurements as well as for flask sampling to derive the climatology of other greenhouse gases (CH4,S F 6 and N2O), is presented.
