Using explainable AI to diagnose the representation of environmental drivers in process-based soil organic carbon models Open
The accuracy of soil organic carbon (SOC) models and their ability to capture the relationship between SOC and environmental variables are critical for reducing uncertainties in future projection of soil carbon balance. In this study, we e…

Dramatic biases in terrestrial nitrogen fixation in Earth System Models revealed by natural isotope signatures Open
Biological nitrogen fixation (BNF) is the primary input of new reactive nitrogen to natural terrestrial ecosystems. However, this flux is poorly constrained due to its unclear drivers and associated control mechanisms. Here, we extend the …

Representing high-latitude deep carbon in the pre-industrial state of the ORCHIDEE-MICT land surface model (r8704) Open
Field measurements, after extrapolation, suggest that deep Yedoma deposits (ice-rich, organic-rich permafrost, formed during the late Pleistocene) and peatlands (formed mostly during the Holocene) account for about 600 Pg C of soil carbon …

Diagnosing linearity along the carbon cascade in terrestrial biosphere models Open
Elevated carbon dioxide (eCO 2 ) fertilises photosynthesis, driving an increase in terrestrial gross primary production (GPP). However, it is unclear how effectively increased GPP propagates along the “carbon (C) cascade” to increase net p…

Spatially varying parameters improve carbon cycle modeling in the Amazon rainforest with ORCHIDEE r8849 Open
Uncertainty in the dynamics of the Amazon rainforest poses a critical challenge for accurately modeling the global carbon cycle. Current dynamic global vegetation models (DGVMs), which use one or two plant functional types for tropical rai…
Divergent responses of carbon and nitrogen functional genes composition to enhanced rock weathering Open
Enhanced rock weathering (ERW) is a scalable strategy for atmospheric carbon dioxide removal. The microbiome function critically regulates the below-ground cycle of carbon and nitrogen in terrestrial ecosystems. However, microbial function…

Resolving effects of leaf pigmentation changes and plant residue on the energy balance of winter wheat cultivation in the ORCHIDEE-CROP model Open
Crop management impacts climate not only through changes in carbon stocks and greenhouse gas budgets, but also through changes in the heat budget. However, the latter aspect is not yet covered by existing cropping system models. The coupli…

Quantification of the biogeophysical impact of crop residue management in Europe Open
Managing jointly the biogeochemical and biogeophysical (e.g. albedo and energy fluxes) impacts of agriculture is essential towards reaching climate-neutral agriculture. Only few observations collected in a small number of sites are availab…
Integrating the effect of microbial legacy and adaptation on soil biogeochemistry in the MIcrobial-MIneral Carbon Stabilization (MIMICS) model.  Open
As an essential process in the global carbon cycle, litter decomposition functions both as a means of carbon loss from soil through microbial respiration and as a contributor to the soil carbon pool. While traditional controls such as clim…
Modeling biochar effects on soil organic carbon on croplands in a microbial decomposition model (MIMICS-BC_v1.0) Open
Biochar (BC) application in croplands aims to sequester carbon and improve soil quality, but its impact on soil organic carbon (SOC) dynamics is not represented in most land models used for assessing land-based climate mitigation, therefor…
A synthesis of phosphorus stocks and fluxes in natural and agricultural environments Open
Estimates of phosphorus (P) fluxes at the global scale were already available in the early 2010s and led to the establishment of planetary boundaries for P. In the meantime, estimates of P stocks and fluxes have been revised and updated fo…

Modelling soybean growth processes in the land surface model ORCHIDEE-CROP Open
Soybean, the most produced leguminous crop on Earth, serves as a vital source of vegetable oil and a major provider of protein for animal feed and human consumption. By fixing atmospheric nitrogen via rhizobia, soybean reduces reliance on …

Representing high-latitude deep carbon in the pre-industrial state of the ORCHIDEE-MICT land surface model (r8704) Open
Field measurements, after extrapolation, suggest that deep Yedoma deposits (formed during the Pleistocene) and peatlands (formed during the Holocene) account for over 700 Pg C of soil carbon storage. Incorporating this old, deep, cold carb…

Low latency carbon budget analysis reveals a large decline of the land carbon sink in 2023 Open
In 2023, the CO2 growth rate was 3.37 ± 0.11 ppm at Mauna Loa, which was 86% above that of the previous year and hit a record high since observations began in 1958, while global fossil fuel CO2 emissions only increased by 0.6% ± 0.5%. This…

Emerging multiscale insights on microbial carbon use efficiency in the land carbon cycle Open
Microbial carbon use efficiency (CUE) affects the fate and storage of carbon in terrestrial ecosystems, but its global importance remains uncertain. Accurately modeling and predicting CUE on a global scale is challenging due to inconsisten…
Impacts of land-use change on biospheric carbon: an oriented benchmark using the ORCHIDEE land surface model Open
