A Bayesian sequential updating approach to predict phenology of silage maize [PDF]

open access: yesBiogeosciences, 2022
Crop models are tools used for predicting year-to-year crop development on field to regional scales. However, robust predictions are hampered by uncertainty in crop model parameters and in the data used for calibration.

High-resolution CMIP6 climate projections for Ethiopia using the gridded statistical downscaling method

open access: yesScientific Data, 2023
High-resolution climate model projections for a range of emission scenarios are needed for designing regional and local adaptation strategies and planning in the context of climate change. To this end, the future climate simulations of global circulation

The role of Phragmites in the CH4 and CO2 fluxes in a minerotrophic peatland in southwest Germany [PDF]

open access: yesBiogeosciences, 2016
Peatlands are interesting as a carbon storage option, but are also natural emitters of the greenhouse gas methane (CH4). Phragmites peatlands are particularly interesting due to the global abundance of this wetland plant (Phragmites australis) and the ...

Energy balance closure on a winter wheat stand: comparing the eddy covariance technique with the soil water balance method [PDF]

open access: yesBiogeosciences, 2016
The energy balance of eddy covariance (EC) flux data is typically not closed. The nature of the gap is usually not known, which hampers using EC data to parameterize and test models.

Spatiotemporal Characteristics of Vegetation Cover and Climate Driving Factors in Sichuan Province from 2000 to 2020

open access: yesShuitu baochi tongbao, 2022
[Objective] The vegetation change and important climate factors influencing fractional vegetation coverage (FVC) in Sichuan Province were analyzed in order to provide theoretical support for the sustainable development of natural resources in this area. [

Optimisation of the seedball technology for sorghum production under nutrient limitations

open access: yesJournal of Agriculture and Rural Development in the Tropics and Subtropics, 2021
The seedball technology is a simple and affordable seed-pelleting technique that uses locally available materials such as sand, loam, wood ash and seeds to enhance early crop establishment.

Spatial Control of Carbon Dynamics in Soil by Microbial Decomposer Communities

open access: yesFrontiers in Environmental Science, 2020
Trait-based models have improved the understanding and prediction of soil organic matter dynamics in terrestrial ecosystems. Microscopic observations and pore scale models are now increasingly used to quantify and elucidate the effects of soil ...

On the use of the post-closure methods uncertainty band to evaluate the performance of land surface models against eddy covariance flux data [PDF]

open access: yesBiogeosciences, 2015
The energy balance of eddy covariance (EC) flux data is normally not closed. Therefore, at least if used for modelling, EC flux data are usually post-closed, i.e. the measured turbulent fluxes are adjusted so as to close the energy balance.

Predicting a Suitable Distribution Pattern of Dominant Tree Species in the Northwestern Sichuan Plateau Under Climate Change and Multi-Scenario Evaluation of Carbon Sink Potentials

open access: yesFrontiers in Environmental Science, 2022
Climate change threatens the global living environment, and afforestation-based carbon sequestration is an effective measure to relieve and adapt to climate changes.
