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...
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...
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.
Modeling the impact of sub-grid scale emission variability on upper-air concentration
sub-grid scale emission upper-air concentration
2008/10/27
The long standing issue of sub-grid emission heterogeneity and its influence to upper air concentration is addressed here and a subgrid model proposed. The founding concept of the approach is the assu...
