Application of boot statistical package in calculating pollutant spreading in air

The issue of modelling the pollutant spreading in air requires a number of decisions to be taken in order to ensure a proper selection of the model option in terms of meteorology or dispersion coefficients. The difference in the results of the calculations of the pollution conditions is observed after each change of option. Negative and positive components of Fractional Bias (FB) or Geometric Mean Bias (MG) may prove to be especially useful, relatively new statistical indicators. They allow the overestimation or underestimation of the results in the case of calculating the pollution distribution within the specified area to be evaluated.
