EMPOWER-1.0:an Efficient Model of Planktonic ecOsystems WrittEn in R
EMPOWER-1.0 Planktonic ecOsystems WrittEn in R
2015/8/6
Modelling marine ecosystems requires insight and judgement when it comes to deciding upon appropriate model structure, equations and parameterisation. Many processes are relatively poorly understood a...
DYPTOP: a cost-efficient TOPMODEL implementation to simulate sub-grid spatio-temporal dynamics of global wetlands and peatlands
global wetlands peatlands
2014/12/19
Simulating the spatio-temporal dynamics of inundation is key to understanding the role of wetlands under past and future climate change. Earlier modelling studies have mostly relied on fixed prescribe...
C-GEM (v 1.0): a new, cost-efficient biogeochemical model for estuaries and its application to a funnel-shaped system
cost-efficient biogeochemical model estuaries and its application funnel-shaped system
2014/12/19
Reactive transport models (RTMs) are powerful tools for disentangling the complex process interplay that drives estuarine biogeochemical dynamics, for assessing the quantitative role of estuaries in g...
IPR 1.0: an efficient method for calculating solar radiation absorbed by individual plants in sparse heterogeneous woody plant communities
an efficient method calculating solar radiation absorbed by individual plants sparse heterogeneous woody plant communities
2014/12/19
Climate change may alter the spatial distribution, composition, structure and functions of plant communities. Transitional zones between biomes, or ecotones, are particularly sensitive to climate chan...
Application of a computationally efficient method to approximate gap model results with a probabilistic approach
computationally efficient method approximate gap model results probabilistic approach
2014/12/19
To be able to simulate climate change effects on forest dynamics over the whole of Switzerland, we adapted the second-generation DGVM (dynamic global vegetation model) LPJ-GUESS (Lund–Potsdam–Jena Gen...
Using model reduction to predict the soil-surface C18OO flux: an example of representing complex biogeochemical dynamics in a computationally efficient manner
Using model reduction predict the soil-surface C18OO flux representing complex biogeochemical dynamics computationally efficient manner
2014/12/16
Earth system models (ESMs) must calculate large-scale interactions between the land and atmosphere while accurately characterizing fine-scale spatial heterogeneity in water, carbon, and other nutrient...
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...
An efficient method to generate a perturbed parameter ensemble of a fully coupled AOGCM without flux-adjustment
An efficient method generate a perturbed parameter ensemble fully coupled AOGCM without flux-adjustment
2014/12/12
We present a simple method to generate a perturbed parameter ensemble (PPE) of a fully-coupled atmosphere-ocean general circulation model (AOGCM), HadCM3, without requiring flux-adjustment. The aim wa...

2014/12/10
The separation of global radiation (Rg) into its direct (Rb) and diffuse constituents (Rg) is important when modeling plant photosynthesis because a high Rd:Rg ratio has been shown to enhance Gross Pr...
TopoSUB: a tool for efficient large area numerical modelling in complex topography at sub-grid scales
Global climate change the environment high resolution model grid lateral variation grid climate data sets
2014/12/10
Mountain regions are highly sensitive to global climate change. However, large scale assessments of mountain environments remain problematic due to the high resolution required of model grids to captu...
