Limiting the parameter space in the Carbon Cycle Data Assimilation System (CCDAS)
Limiting the parameter space Carbon Cycle Data Assimilation System
2014/12/19
Terrestrial ecosystem models are employed to calculate the sources and sinks of carbon dioxide between land and atmosphere. These models may be heavily parameterised. Where reliable estimates are unav...
Modeling sugarcane yield with a process-based model from site to continental scale: uncertainties arising from model structure and parameter values
Modeling sugarcane yield continental scale

Agro-land surface models (agro-LSM) have been
developed from the integration of specific crop processes into
large-scale generic land surface models that allow calculating
the spatial distrib...

2014/12/18
Modern land surface model simulations capture
soil profile water movement through the use of soil hydraulics sub-models, but good hydraulic parameterisations
are often lacking, especially in t...
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...
An optimally tuned ensemble of the "eb_go_gs" configuration of GENIE: parameter sensitivity and bifurcations in the Atlantic overturning circulation
optimally tuned ensemble eb_go_gs configuration of GENIE parameter sensitivity and bifurcations Atlantic overturning circulation
2014/12/12
The key physical parameters for the "eb_go_gs" configuration of version 2.7.4 of GENIE, an Earth system model of intermediate complexity (EMIC), are tuned using a multi-objective genetic algorithm. An...
Application of the Bayesian calibration methodology for the parameter estimation in CoupModel
Bayesian calibration methodology CoupModel
2010/2/3
This study provides results for the optimization strategy of highly parameterized models, especially with a high number of unknown input parameters and joint problems in terms of sufficient parameter ...
Rockfall hazard mapping along a mountainous road in Switzerland using a GIS-based parameter rating approach
Rockfall hazard mapping a mountainous road Switzerland a GIS-based parameter rating approach
2009/12/10
A posteriori studies of rock slope instabilities generally show that rockfalls do not occur at random locations: the failure zone can be classified as sensitive from geomorphological evidence. Zones s...
Is flow velocity a significant parameter in flood damage modelling?
flow velocity significant parameter flood damage modelling
2009/12/8
Flow velocity is generally presumed to influence flood damage. However, this influence is hardly quantified and virtually no damage models take it into account. Therefore, the influences of flow veloc...
Influences of observation errors in eddy flux data on inverse model parameter estimation
observation errors eddy flux data inverse model parameter estimation
2010/1/18
Eddy covariance data are increasingly used to estimate parameters of ecosystem models. For proper maximum likelihood parameter estimates the error structure in the observed data has to be fully charac...
Using Bayesian methods for the parameter estimation of deformation monitoring networks
Bayesian methods the parameter estimation deformation monitoring networks
2009/12/30
In order to investigate the deformations of an area or an object, geodetic observations are repeated at different time epochs and then these observations of each period are adjusted independently. Fro...
Identifying and reducing model structure uncertainty based on analysis of parameter interaction
model structure uncertainty parameter interaction
2010/1/27
Multi-objective optimization algorithms are widely used for the calibration of conceptual hydrological models. Such algorithms yield a set of Pareto-optimal solutions, reflecting the model structure u...
Investigation of parameter uncertainty and identifiability of the hydrological model WaSiM-ETH
parameter uncertainty and identifiability the hydrological model WaSiM-ETH
2010/1/26
The identification of optimum model parameters may be influenced by temporal or event-specific changes of optimum parameter ranges and the length and information content of calibration data. These eff...
