Modelling methane fluxes along the thawing gradient of Boreal-Arctic peatland ecosystems with CoupModel Open
Northern peatlands are key carbon reservoirs and natural sources of methane. The northern peatland soils have various mechanisms controlling water, energy and carbon cycles (soil freeze-thaw) which further make modeling the emissions a cha…
Coupled water–carbon flux processes of date palms under lysimeter-based saline irrigation: CoupModel calibration and evaluation Open
Date palms are a cash crop and commonly irrigated using saline water. A better understanding of the processes involved in water use by date palms and their carbon budget is key to sustainable cultivation and saline irrigation scheduling. I…
Modelling the northern peatland methane fluxes with a process-based model Open
Northern peatlands are significant carbon reservoirs, serving as long-term atmospheric carbon dioxide sinks and sources of methane and nitrogen dioxide. However, methane processes interacting with environmental changes in Northern peatland…
Modeling the recent drought and thinning impacts on energy, water and carbon fluxes in a boreal forest Open
This dataset includes the data used for model calibration and validation, as well as the simulation files with accepted runs, which are available for the readers to re-generate the results of this work. The *.bin files are the data for dri…

Biotic and abiotic responses of the boreal forests carbon cycles to climate change and management Open
Boreal forests are a large carbon sink and are as important as the tropical forests due to huge carbon stock in both plants and soils. However, the boreal forests carbon sink is affected by climate change on one hand and by management on t…
Modeling coupled nitrification-denitrification in manure-amended soil Open
The flux of nitrous oxide (N2O) from the soil to the atmosphere is an important contributor to the global greenhouse effect. Spatial variation in the distribution of factors that drive N2O producing processes often creates hotspots within …
Modeling nitrous oxide emissions from agricultural soil incubation experiments using CoupModel Open
Efforts to develop effective climate mitigation strategies for agriculture require methods to estimate nitrous oxide (N2O) emissions from soil. Process-based biogeochemical models have been often used for field- and large-scale estimates, …

Proposal and extensive test of a calibration protocol for crop phenology models Open
A major effect of environment on crops is through crop phenology, and therefore, the capacity to predict phenology for new environments is important. Mechanistic crop models are a major tool for such predictions, but calibration of crop ph…

Modelling nitrous oxide emissions from agricultural soil incubation experiments using CoupModel  Open
To develop good mitigation strategies, estimates of nitrous oxide (N2O) emissions from agricultural soils are needed. Process-based biogeochemical models have been used for such estimation but those have mainly been tested on field scaled …

Mosses are Important for Soil Carbon Sequestration in Forested Peatlands Open
Nutrient-rich peat soils have previously been demonstrated to lose carbon despite higher photosynthesis and litter production compared to nutrient-poor soils, where instead carbon accumulates. To understand this phenomenon, we used a proce…

Simulated or measured soil moisture: which one is adding more value to regional landslide early warning? Open
The inclusion of soil wetness information in empirical landslide prediction models was shown to improve the forecast goodness of regional landslide early warning systems (LEWSs). However, it is still unclear which source of information – n…
Modelling Impacts of Lateral N Flows And Seasonal Warming on an Arctic Footslope Ecosystem N Budget and N2O Emissions Based on Species-Level Responses Open
Future Arctic tundra primary productivity and vegetation community composition will partly be determined by nitrogen (N) availability in a warmer climate. N mineralization rates are predicted to increase in winter and summer, but because N…
Nitrogen Transport in a Tundra Landscape: The Effects of Early and Late Growing Season Lateral N Inputs on Arctic Soil and Plant N Pools and N2O Fluxes Open
Understanding N budgets of tundra ecosystems is crucial for projecting future changes in plant community composition, greenhouse gas balances and soil N stocks. Winter warming can lead to higher tundra winter nitrogen (N) mineralization ra…

CoupModel (v6.0): an ecosystem model for coupled phosphorus, nitrogen, and carbon dynamics – evaluated against empirical data from a climatic and fertility gradient in Sweden Open
This study presents the integration of the phosphorus (P) cycle into CoupModel (v6.0, referred to as Coup-CNP). The extended Coup-CNP, which explicitly considers the symbiosis between soil microbes and plant roots, enables simulations of c…
