摘要

The normalized integrated concentration of pollutant has been obtained after solving temporaly diffusion equation using the method of separation variable considering the eddy diffusivities which measuring at night or at any time in high inversion layer in the stable condition. The dataset is observed from the “Project prairie Grass” (Barad 1958) which is measured using wind speed at 1.5m and downwind distance during the experiment at i50, 200/i and i800 m/i in stable case for runs from 1 to 10. Comparison between the estimated and observed normalized integrated concentration at a different downwind distance for all runs at it/i = 30 minutes is calculated.
