Electricity generation and distribution infrastructure in the Western United States must be “climate-proofed” to diminish the risk of future power shortages, according to research by two Arizona State...
Development and application of a reactive plume-in-grid model: evaluation over Greater Paris
a reactive plume-in-grid model Greater Paris
2010/10/11
Emissions from major point sources are badly represented by classical Eulerian models. An overestimation of the horizontal plume dilution, a bad representation of the vertical diffusion as well as an ...
An investigation of the sub-grid variability of trace gases and aerosols for global climate modeling
the sub-grid variability trace gases and aerosols global climate modeling
2010/8/16
One fundamental property and limitation of grid based models is their inability to identify spatial details smaller than the grid cell size. While decades of work have gone into developing sub-grid tr...
Stochastic fields method for sub-grid scale emission heterogeneity in mesoscale atmospheric dispersion models
Stochastic fields method sub-grid scale emission heterogeneity mesoscale atmospheric dispersion models
2010/1/18
The stochastic fields method for turbulent reacting flows has been applied to the issue of sub-grid scale emission heterogeneity in a mesoscale model. This method is a solution technique for the proba...
Grid resolution dependence in the reconstruction of an atmospheric tracer source
Grid resolution dependence reconstruction atmospheric tracer source
2009/11/9
Methods for reconstructing sources of inert atmospheric tracers from ground measurements are currently studied, tested, and even implemented (in accident-type radionuclide release backtracking, for re...
Regional CO pollution and export in China simulated by the high-resolution nested-grid GEOS-Chem model
Regional CO pollution high-resolution nested-grid GEOS-Chem model
2009/6/16
An updated version of the nested-grid GEOS-Chem model is developed allowing for higher horizontal (0.5°×0.667°) resolution as compared to global models. CO transport over a heavily polluted region, th...
The impact of model grid zooming on tracer transport in the 1999/2000 Arctic polar vortex
model grid zooming tracer transport Arctic polar vortex
2009/3/11
We have used a 3D chemistry transport model to evaluate the transport of HF and CH4 in the stratosphere during the Arctic winter of 1999/2000. Several model experiments were carried out with the use o...
A quantitative analysis of grid-related systematic errors in oxidising capacity and ozone production rates in chemistry transport models
grid-related systematic errors oxidising capacity ozone production rates chemistry transport models
2009/3/5
Limited resolution in chemistry transport models (CTMs) is necessarily associated with systematic errors in the calculated chemistry, due to the artificial mixing of species on the scale of the model ...
Including the sub-grid scale plume rise of vegetation fires in low resolution atmospheric transport models
sub-grid scale vegetation fires atmospheric transport models
2008/11/12
We describe and begin to evaluate a parameterization to include the vertical transport of hot gases and particles emitted from biomass burning in low resolution atmospheric-chemistry transport models.
