Optimization of a prognostic biosphere model for terrestrial biomass and atmospheric CO2 variability
prognostic biosphere model terrestrial biomass atmospheric CO2 variability
<
2014/12/19
This study investigates the capacity of a prognostic biosphere model to simulate global variability in atmospheric CO2 concentrations and vegetation carbon dynamics under current environmental conditi...
Interactive coupling of regional atmosphere with biosphere in the new generation regional climate system model REMO-iMOVE
Interactive coupling regional atmosphere
<
2014/12/18
The main objective of this study is the coupling
of the regional climate model REMO with a new land surface scheme including dynamic vegetation phenology, and
the evaluation of the new model version...
From biota to chemistry and climate: towards a comprehensive description of trace gas exchange between the biosphere and atmosphere
From biota to chemistry and climate trace gas exchange the biosphere and atmosphere
<
2010/1/21
Exchange of non-CO2 trace gases between the land surface and the atmosphere plays an important role in atmospheric chemistry and climate. Recent studies have highlighted its importance for interpretat...
Biosphere-atmosphere exchange of CO2 in relation to climate:a cross-biome analysis across multiple time scales
Biosphere-atmosphere exchange CO2 cross-biome analysis multiple time scales
<
2010/1/21
The net ecosystem exchange of CO2 (NEE) varies at time scales from seconds to years and longer via the response of its components, gross ecosystem productivity (GEP) and ecosystem respiration (RE), to...
Towards global empirical upscaling of FLUXNET eddy covariance observations:validation of a model tree ensemble approach using a biosphere model
global empirical upscaling FLUXNET eddy covariance observations ensemble approach
<
2010/1/21
Global, spatially and temporally explicit estimates of carbon and water fluxes derived from empirical up-scaling eddy covariance measurements would constitute a new and possibly powerful data stream t...
The ACCENT-VOCBAS field campaign on biosphere-atmosphere interactions in a Mediterranean ecosystem of Castelporziano (Rome):site characteristics,climatic and meteorological conditions,and eco-physiology of vegetation
ACCENT-VOCBAS field biosphere-atmosphere interactions Mediterranean ecosystem site characteristics
<
2010/1/20
Biosphere-atmosphere interactions were investigated on a sandy dune Mediterranean ecosystem in a field campaign held in 2007 within the frame of the European Projects ACCENT and VOCBAS. The campaign w...
Incorporation of crop phenology in Simple Biosphere Model (SiBcrop) to improve land-atmosphere carbon exchanges from croplands
crop phenology Simple Biosphere Model land-atmosphere carbon exchanges croplands
<
2010/1/20
Croplands are man-made ecosystems that have high net primary productivity during the growing season of crops, thus impacting carbon and other exchanges with the atmosphere. These exchanges play a majo...
The response of the terrestrial biosphere to urbanization:land cover conversion,climate,and urban pollution
terrestrial biosphere urbanization land cover conversion climate urban pollution
<
2010/1/18
Although urban areas occupy a relatively small fraction of land, they produce major disturbances of the carbon cycle through land use change, climate modification, and atmospheric pollution. In this s...
Multiple steady-states in the terrestrial atmosphere-biosphere system:a result of a discrete vegetation classification?
Multiple steady-states atmosphere-biosphere system discrete vegetation classification
<
2010/1/14
Multiple steady states in the atmosphere-biosphere system can arise as a consequence of interactions and positive feedbacks. While atmospheric conditions affect vegetation productivity in terms of ava...
Causes and timing of future biosphere extinctions
Causes timing future biosphere extinctions
<
2010/1/13
We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the combined ocean and atmo...
