Journal ArticleDOI
Observations and modelling of the global distribution and long-term trend of atmospheric 14CO2
Ingeborg Levin,Tobias Naegler,Bernd Kromer,Moritz Diehl,Roger J. Francey,A. J. Gomez-Pelaez,L. Paul Steele,Dietmar Wagenbach,Rolf Weller,Douglas E. J. Worthy +9 more
TL;DR: In this paper, high-precision atmospheric Δ 14 CO 2 records covering the last two decades are presented, and evaluated in terms of changing (radio)carbon sources and sinks, using the coarse-grid carbon cycle model GRACE.
Journal ArticleDOI
The global SF6 source inferred from long-term high precision atmospheric measurements and its comparison with emission inventories
Ingeborg Levin,Tobias Naegler,R. Heinz,D. Osusko,Emilio Cuevas,Anja Engel,J. Ilmberger,Ray L. Langenfelds,B. Neininger,C. v. Rohden,L. P. Steele,R. Weller,Douglas E. J. Worthy,S. A. Zimov +13 more
TL;DR: In this paper, an extended data set of globally distributed high-precision sulphur hexafluoride (SF6) observations shows an increase in SF6 abundance from near zero in the 1970s to a global mean of 6.7 ppt by the end of 2008.
Journal ArticleDOI
On the use of 14CO2 as a tracer for fossil fuel CO2: Quantifying uncertainties using an atmospheric transport model
Jocelyn Turnbull,Peter Rayner,John B. Miller,John B. Miller,Tobias Naegler,Philippe Ciais,Anne Cozic +6 more
TL;DR: In this paper, the LMDZ global atmospheric transport model was used to examine the pseudo-Lagrangian framework commonly used to determine recently added fossil fuel CO2 (CO2ff).
Journal ArticleDOI
Excess radiocarbon constraints on air‐sea gas exchange and the uptake of CO2 by the oceans
TL;DR: In this article, the authors re-assess the constraints that estimates of the global ocean excess radiocarbon inventory place on air-sea gas exchange and develop a new wind speed and inventory-normalized gas exchange parameter aqN which takes into account these biases and which is easily adaptable to any new estimate of the ocean excess carbon inventory.
Journal ArticleDOI
Closing the global radiocarbon budget 1945–2005
Tobias Naegler,Ingeborg Levin +1 more
TL;DR: In this paper, the authors estimate the range of uncertainty in the explosive force of atmospheric nuclear bomb tests and their respective 14C yield factor using available stratospheric and tropospheric radiocarbon (14C) observations as constraints.
