Abstract

The proposed concentrations model was compared to observed data from air diffusion studies for hexafluoride (SF6) conducted in the northern area of Copenhagen, Denmark, and earlier work for the Gaussian puff model. The predicted concentrations and earlier studies were found to be within a factor of two of each other, indicating that the predicted data is compatible with the observed concentrations data. Under unstable conditions, the statistical statistics show a reasonable agreement between the expected and observed concentrations at the Copenhagen Experimental. In contrast to the previous work's results, which had an NMSE of 0.3 and an FB of 0.21, we discovered that the data obtained using the statistical method had an NMSE of 0.2 and an FB of 0.25. The projected COR is 0.95, compared to 0.97 in a previous computation. The observed concentration data was 88% of the expected value, compared to 78% in previous research. The expected data are consistent with the observed concentration measurements. When compared to previous work, the Copenhagen experiment was conducted under unstable conditions, and statistical data show good agreement between predicted and observed concentrations.
