Abstract. Global terrestrial nitrogen (N) and phosphorus (P) cycles are coupled to the global carbon (C) cycle for net primary production (NPP), plant C allocation, and decomposition of soil organic matter, but N and P h...
-
A wide range of research shows that nutrient availability strongly influences terrestrial carbon (C) cycling and shapes ecosystem responses to environmental changes and hence terrestrial feedbacks to climate. Nonetheless...
-
Large interannual variations in the measured growth rate of atmospheric carbon dioxide (CO2) originate primarily from fluctuations in carbon uptake by land ecosystems1,2,3. It remains uncertain, however, to what extent t...
-
Recent advances in the representation of soil carbon decomposition and carbon-nitrogen interactions implemented previously into separate versions of the land surface scheme JSBACH are here combined in a single version, w...

The ability of a Bayesian atmospheric inversion to quantify the Paris region's fossil fuel CO 2 emissions on a monthly basis, based on a network of three surface stations operated for 1 year as part of the CO 2-MEGAPARIS...
-
Carbon uptake by terrestrial ecosystems is increasing along with the rising of atmospheric CO 2 concentration. Embedded in this trend, recent studies suggested that the interannual variability (IAV) of global carbon flux...
-
A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectivenes...

Climate change may pose a high risk of change to Earth's ecosystems: shifting climatic boundaries may induce changes in the biogeochemical functioning and structures of ecosystems that render it difficult for endemic pla...

Evaluating the land and ocean components of the global carbon cycle in the CMIP5 earth system modelsThe authors assess the ability of 18 Earth system models to simulate the land and ocean carbon cycle for the present climate. These models will be used in the next Intergovernmental Panel on Climate Change (IPCC) Fifth A...
-
Northern peatlands are likely to be important in future carbon cycle-climate feedbacks due to their large carbon pools and vulnerability to hydrological change. Use of non-peatland-specific models could lead to bias in m...
-
Land models, which have been developed by the modeling community in the past few decades to predict future states of ecosystems and climate, have to be critically evaluated for their performance skills of simulating ecos...

[1] We present the results of a validation of atmospheric inversions of CO 2 fluxes using four transport models. Each inversion uses data primarily from surface stations, combined with an atmospheric transport model, to ...
-
Terrestrial gross primary production (GPP) is the largest global CO$_2$ flux driving several ecosystem functions. We provide an observation-based estimate of this flux at 123$\pm$8 petagrams of carbon per year (Pg C year...

An inverse model using atmospheric CO 2 observations from a European network of stations to reconstruct daily CO 2 fluxes and their uncertainties over Europe at 50 km resolution has been developed within a Bayesian frame...
