Modelling the role of fires in the terrestrial carbon balance by incorporating SPITFIRE into the global vegetation model ORCHIDEE – Part 1: simulating historical global burned area and fire regimes
simulating historical global burned area fire regimes
2014/12/19
Fire is an important global ecological process that influences the distribution of biomes, with consequences for carbon, water, and energy budgets. Therefore it is impossible to appropriately model th...
Autumn temperature and carbon balance of a boreal Scots pine forest in Southern Finland
Autumn temperature carbon balance a boreal Scots pine forest Southern Finland
2010/1/21
We analyzed the dynamics of carbon balance components: gross primary production (GPP) and total ecosystem respiration (TER), of a boreal Scots pine forest in Southern Finland. The main focus is on inv...
An outlook on the Sub-Saharan Africa carbon balance
outlook Sub-Saharan Africa carbon balance
2010/1/21
This study gives an outlook on the carbon balance of Sub-Saharan Africa (SSA) by presenting a summary of currently available results from the project CarboAfrica (namely net ecosystem productivity and...
Variability and recent trends in the African terrestrial carbon balance
Variability recent trends African terrestrial carbon balance
2010/1/21
We modeled the African terrestrial carbon balance over the past century using a spatially resolved process based vegetation model (ORCHIDEE). The model is forced by changing climate and by human-induc...
The impact of lateral carbon fluxes on the European carbon balance
impact lateral carbon fluxes European carbon balance
2010/1/18
To date, little is known about the impact of processes which cause lateral carbon fluxes over continents, and from continents to oceans on the CO2 – and carbon budgets at local, regional and continent...
Towards operational remote sensing of forest carbon balance across Northern Europe
operational remote sensing forest carbon balance Northern Europe
2010/1/15
Monthly averages of ecosystem respiration (ER), gross primary production (GPP) and net ecosystem exchange (NEE) over Scandinavian forest sites were estimated using regression models driven by air temp...
Competing roles of rising CO2 and climate change in the contemporary European carbon balance
Competing roles rising CO2 d climate change European carbon balance
2010/1/15
Natural ecosystems respond to, and may affect climate change through uptake and storage of atmospheric CO2. Here we use the land-surface and carbon cycle model JULES to simulate the contemporary Europ...
CO2 exchange and carbon balance in two grassland sites on eutrophic drained peat soils
CO2 exchange carbon balance grassland sites eutrophic drained peat soils
2010/1/14
In this study we investigated the role of intensive and extensive dairy farm practices on CO2 exchange and the carbon balance of peatlands by means of eddy covariance (EC) measurements. Year long EC m...
An airborne regional carbon balance for Central Amazonia
airborne regional carbon balance Central Amazonia
2010/1/14
We obtained regional estimates of surface CO2 exchange rates using atmospheric boundary layer budgeting techniques above tropical forest near Manaus, Brazil. Comparisons were made with simultaneous me...
Carbon balance assessment of a natural steppe of southern Siberia by multiple constraint approach
Carbon balance assessment natural steppe southern Siberia multiple constraint approach
2010/1/14
Steppe ecosystems represent an interesting case in which the assessment of carbon balance may be performed through a cross validation of the eddy covariance measurements against ecological inventory e...
Soils apart from equilibrium – consequences for soil carbon balance modelling
Soils equilibrium consequences soil carbon balance modelling
2010/1/14
Many projections of the soil carbon sink or source are based on kinetically defined carbon pool models. Para\-meters of these models are often determined in a way that the steady state of the model ma...
