Journal ArticleDOI
Regional-scale CO 2 fluxes over central Sweden by a boundary layer budget method
Peter Levy,Achim Grelle,Anders Lindroth,Meelis Mölder,Paul G. Jarvis,Bart Kruijt,John Moncrieff +6 more
TL;DR: In this paper, the authors used free-flight radiosondes to measure the height of the convective boundary layer (CBL) over four days in summer 1997, and found good agreement on two days when the airmass was maritime in origin, and the CO2 mixing ratio above the CBL (Ct) could be assumed to be equivalent to values measured at oceanic sites.
Journal ArticleDOI
The Full Annual Carbon Balance of Boreal Forests Is Highly Sensitive to Precipitation
Mats G. Öquist,Kevin Bishop,Kevin Bishop,Achim Grelle,Leif Klemedtsson,Stephan Jürgen Köhler,Hjalmar Laudon,Anders Lindroth,M. Ottosson Lofvenius,Marcus B. Wallin,Mats Nilsson +10 more
TL;DR: In this article, the lateral carbon export (LCE) at a boreal forest site ranged from 4 to 28%, averaging 11% (standard deviation of 8%) of annual LCE over 13 years.
Journal ArticleDOI
Carbon dioxide exchange in Norway spruce at the shoot, tree and ecosystem scale.
TL;DR: Most of the measured variation in carbon exchange rate among the shoot, tree and ecosystem levels was the result of periodic low coupling between vegetation and the atmosphere at the ecosystem level.
Journal ArticleDOI
Flux partitioning between understorey and overstorey in a boreal spruce/pine forest determined by the eddy covariance method
TL;DR: In this paper, the eddy covariance method was used to determine turbulent heat fluxes and carbon dioxide fluxes inside a boreal spruce ‐ pine forest during the growing season in 1994 and 1995.
Journal ArticleDOI
Analysis of carbon and water fluxes from the NOPEX boreal forest: comparison of measurements with FOREST-BGC simulations
TL;DR: In this paper, the FOREST-BGC model was applied on a stand in the NOPEX region in central Sweden and compared with measured data of net ecosystem carbon flux (F n ) and transpiration (E Q ) on a daily basis.
