Vegetation growth in Northern Hemisphere stunted by water constraints in warming climate
warming climate water constraints vegetation growth greenhouse gass
2021/8/4
A new study of vegetation growth in the Northern Hemisphere over the past 30 years has found that vegetation is becoming increasingly water-limited as global temperatures increase, which has the poten...
Response of the water use efficiency of natural vegetation to drought in Northeast China
natural vegetation drought water use efficiency (WUE)
2018/4/9
Drought has become a problem that is universally faced by global terrestrial ecosystems. Northeast China is located in a region sensitive to global climate changes, and one of the main impacts of clim...
Improving the dynamics of Northern Hemisphere high-latitude vegetation in the ORCHIDEE ecosystem model
Northern Hemisphere high-latitude vegetation ORCHIDEE ecosystem model
2015/8/6
Processes that describe the distribution of vegetation and ecosystem succession after disturbance are an important component of dynamic global vegetation models (DGVMs). The vegetation dynamics module...
Improved simulation of fire–vegetation interactions in the Land surface Processes and eXchanges dynamic global vegetation model (LPX-Mv1)
fi re–vegetation interactions Land surface Processes
2014/12/19
The Land surface Processes and eXchanges (LPX)
model is a fire-enabled dynamic global vegetation model
that performs well globally but has problems representing
fire regimes and vegetat...
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...
Effects of vegetation structure on biomass accumulation in a Balanced Optimality Structure Vegetation Model (BOSVM v1.0)
Balanced Optimality Structure Vegetation Model vegetation structure
2014/12/18
A myriad of interactions exist between vegetation
and local climate for arid and semi-arid regions. Vegetation
function, structure and individual behavior have large impacts on carbon–water–energy b...
GAPPARD: a computationally efficient method of approximating gap-scale disturbance in vegetation models
GAPPARD computationally efficient method approximating gap-scale disturbance vegetation models
2014/12/12
Models of vegetation dynamics that are designed for application at spatial scales larger than individual forest gaps suffer from several limitations. Typically, either a population average approximati...
Quantifying the carbon uptake by vegetation for Europe on a 1 km2 resolution using a remote sensing driven vegetation model
Quantifying the carbon uptake Europe on a 1 km2 resolution remote sensing driven vegetation model
2014/12/12
In this study we compare monthly gross primary productivity (GPP) time series (2000–2007), computed for Europe with the Biosphere Energy Transfer Hydrology (BETHY/DLR) model with monthly data from the...
Vegetation height and cover fraction between 60° S and 60° N from ICESat GLAS data
Vegetation height cover fraction 60° S and 60° N ICESat GLAS data
2014/12/11
We present new coarse resolution (0.5° × 0.5°) vegetation height and vegetation-cover fraction data sets between 60° S and 60° N for use in climate models and ecological models. The data sets are deri...
Inclusion of vegetation in the Town Energy Balance model for modelling urban green areas
vegetation Town Energy Balance model modelling urban green areas
2014/12/10
Cities impact both local climate, through urban heat islands and global climate, because they are an area of heavy greenhouse gas release into the atmosphere due to heating, air conditioning and traff...
A new dust cycle model with dynamic vegetation: LPJ-dust version 1.0
dust cycle model dynamic vegetation LPJ-dust version 1.0
2014/12/9
This paper presents a new offline dust cycle model which uses the Lund-Potsdam-Jena dynamic global vegetation model (Sitch et al., 2003) to calculate time varying dust sources. Surface emissions are c...
