Abstract :
A datacube model for atmospheric pollutants is presented in this work. The value of interest is flux of pollutant deposition versus several attributes such as pollutant type, location, geographic scale, etc. We present also an analytical model for the effect of wind gusts on the pollutant distribution. The model takes into account random variations in wind speed and instrumentation noise. We consider the case of a figures neutrally buoyant plume emitted from an elevated point source in a turbulent boundary layer. The results show that wind turbulence is an important factor in the dispersion plume distribution and leads to spreading the distribution due to wind mixing.
