Analysis of the NLR airports pollution dispersion model on sensitivity for meteorological parameters and on source modeling

The NLR airports pollution dispersion model is analysed with regard to sensitivity for meteorological parameters and the modeling of the sources of pollution (i.e. airplanes). It is found that the weather resolution of the model is satisfactory in view of the present standards of meteorological measurement. Atmospheric stability (Pasquill class)...
