Implications of the steady-state assumption for the global vegetation carbon turnover

Naixin Fan; Maurizio Santoro; Simon Besnard dkk.

Environmental Research Letters, Vol. 18 No. 10 · 2023 · Inggris · DOAJ Scopus

Vegetation carbon turnover time ( τ ) is a central ecosystem property to quantify the global vegetation carbon dynamics. However, our understanding of vegetation dynamics is hampered by the lack of long-term observations of the changes in vegetation biomass. Here we challenge the steady state…

Scaling carbon fluxes from eddy covariance sites to globe: synthesis and evaluation of the FLUXCOM approach

Martin Jung; Christopher R. Schwalm; Mirco Migliavacca dkk.

Biogeosciences · 2020 · Inggris · OpenAlex Scopus

FLUXNET comprises globally distributed eddy-covariance-based estimates of carbon fluxes between the biosphere and the atmosphere. Since eddy covariance flux towers have a relatively small footprint and are distributed unevenly across the world, upscaling the observations is necessary to obtain…

Memory effects of climate and vegetation affecting net ecosystem CO 2 fluxes in global forests

Simon Besnard; Nuno Carvalhais; M. Altaf Arain dkk.

PLOS ONE, Vol. 14 No. 2 · 2019 · Inggris · PLOS Scopus

Forests play a crucial role in the global carbon (C) cycle by storing and sequestering a substantial amount of C in the terrestrial biosphere. Due to temporal dynamics in climate and vegetation activity, there are significant regional variations in carbon dioxide (CO2) fluxes between the biosphere…

Ecosystem transpiration and evaporation: Insights from three water flux partitioning methods across FLUXNET sites

Jacob A. Nelson; Óscar Pérez‐Priego; Sha Zhou dkk.

Global Change Biology · 2020 · Inggris · OpenAlex Scopus

We apply and compare three widely applicable methods for estimating ecosystem transpiration (T) from eddy covariance (EC) data across 251 FLUXNET sites globally. All three methods are based on the coupled water and carbon relationship, but they differ in assumptions and parameterizations…

Quantifying the effect of forest age in annual net forest carbon balance

Simon Besnard; Nuno Carvalhais; M Altaf Arain dkk.

Environmental Research Letters, Vol. 13 No. 12 · 2018 · Inggris · DOAJ Scopus

Forests dominate carbon (C) exchanges between the terrestrial biosphere and the atmosphere on land. In the long term, the net carbon flux between forests and the atmosphere has been significantly impacted by changes in forest cover area and structure due to ecological disturbances and management…
