Turbulent transport, emissions and the role of compensating errors in chemical transport models
Turbulent transport emissions
2014/12/18
The balance between turbulent transport and emissions is a key issue in understanding the formation of O3 and
particulate matter with diameters less than 2.5 μm (PM2.5)Discrepancies between observed ...

Mass-Transport Models with Multiple-Chipping Processes
Mass-Transport Models Multiple-Chipping Processes
2010/11/22
We study mass-transport models with multiple-chipping processes. The rates of these processes are dependent on the chip size and mass of the fragmenting site. In this context, we consider k-chip moves...

The implementation and application of a newly developed coupled system combining ECMWF's integrated forecast system (IFS) with global chemical transport models (CTMs) is presented. The main objective ...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
A new European plant-specific emission inventory of biogenic volatile organic compounds for use in atmospheric transport models

2009/3/11
A rigorous evaluation of five global Chemistry-Transport and two Chemistry-Climate Models operated by several different groups in Europe, was performed. Comparisons were made of the models with trace ...
On the use of mass-conserving wind fields in chemistry-transport models
mass-conserving wind fields chemistry-transport models
2009/3/10
A new method has been developed that provides mass-conserving wind fields for global chemistry-transport models. In previous global Eulerian modeling studies a mass-imbalance was found between the mod...
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 ...
