Fluid Simulations with Localized Boltzmann Upscaling by Direct Simulation Monte-Carlo
Localized Boltzmann Upscaling Simulation Monte-Carlo
2010/11/18
In the present work, we present a novel numerical algorithm to couple the Direct Simulation Monte Carlo method (DSMC) for the solution of the Boltzmann equation with a finite volume like method for t...
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...
Modelling basin-wide variations in Amazon forest productivity – Part 1:Model calibration,evaluation and upscaling functions for canopy photosynthesis
basin-wide variations Amazon forest productivity Model calibration evaluation
2010/1/20
Given the importance of Amazon rainforest in the global carbon and hydrological cycles, there is a need to parameterize and validate ecosystem gas exchange and vegetation models for this region in ord...
Dynamical process upscaling for deriving catchment scale state variables and constitutive relations for meso-scale process models
catchment scale state variables meso-scale process models
2009/5/15
In this study we propose an uspcaling approach to derive time series of (a) REW scale state variables, and (b) effective REW scale soil hydraulic functions to test and parameterise models based on th...
Upscaling of land-surface parameters through direct moment propagation
Upscaling land-surface parameters moment propagation
2010/1/25
A new methodology is presented that allows the upscaling of land surface parameters of a Soil-Vegetation-Atmosphere-Transfer (SVAT) Model. Focus is set on the proper representation of latent and sensi...
Greenhouse gas emissions from Indian rice fields:calibration and upscaling using the DNDC model
Greenhouse gas emissions rice fields calibration upscaling DNDC model
2010/1/12
The Denitrification and Decomposition (DNDC) model was evaluated for its ability to simulate methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) emissions from Indian rice fields with various ...
