Technical note: a new method for the evaluation of puff dispersion field experiments for the validation of time-resolved dispersion simulations

We present a new method for the evaluation of field measurements of atmospheric dispersion at the smallest resolvable time scales. Our method has its origins in the distance-neighbour functions defined by Richardson as well as the auto correlations, spatial correlations and cross correlations commonly used in the turbulence community. We show that a robust quantification of the puff duration can be achieved, which is comparable to the puff duration derived by a dosage-based approach. The new method gives reasonable results without the need to apply thresholds when the concentration measurement is very noisy, which is very advantageous in the context of field measurements.

Abstract

We present a new method for the evaluation of field measurements of atmospheric dispersion at the smallest resolvable time scales. Our method has its origins in the distance-neighbour functions defined by Richardson as well as the auto correlations, spatial correlations and cross correlations commonly used in the turbulence community. We show that a robust quantification of the puff duration can be achieved, which is comparable to the puff duration derived by a dosage-based approach. The new method gives reasonable results without the need to apply thresholds when the concentration measurement is very noisy, which is very advantageous in the context of field measurements.
