Development and regional application of a photochemical oxidant dispersion/reactivity model
In this paper we use the urban airshed model IV, simultaneously including the dispersion and the tropospheric chemistry as described in version IV of the carbon bond (CB-IV). The modelling area covers northern France and a part of Belgium, with a total surface area of 15 000 km2. The wind field is calculated using the Meteo France ALADIN code and temperature vertical profiles from radiosoundings. ...

Three-dimensional modelling of photochemical air pollution in Switzerland and comparison with a multi-parcel Lagrangian model
The photochemical smog situation in Switzerland on 29 July, 1993 was simulated using the 3-D grid model UAM (Urban Airshed Model) and the results were compared with those of a multi-parcel Lagrangian model. Sensitivity analyses concerning initial conditions, emissions, deposition, biogenic volatile organic compounds (VOC), and emission reductions were carried out. Results were compared with field ...

Application of The Air Pollution Model (TAPM) to the urban airshed of Bangkok, Thailand
Bangkok has been faced with air pollution problems as a result of increasing traffic emissions. The Air Pollution Model (TAPM) was employed to simulate carbon monoxide (CO) concentrations based on an emissions inventory data. The hourly CO concentrations from a year-long simulation have been evaluated against observations from six monitoring sites. The simulated concentrations were evaluated ...

Pollution abatement for improving air quality of Tangshan municipality, China: a perspective of urban-airshed carrying-capacity concept
This paper presents a perspective of Urban-Airshed Carrying-Capacity (UACC) concept for air pollution abatement in Tangshan Municipality, China. A 3D Multi-Box Air Quality Prediction (3DMBAQP) model was developed for predicting daily average SO2, TSP and PM10 concentrations in each sub-box of different municipal Function Zones (FZs). A 6-step procedure was designed to determine the UACC levels ...
