Estimation of Lagrangian parameters from a diffusion experiment

Summary Taylor's statistical theory in the limits of small and large diffusion times is used to assess the Lagrangian parameters of a local atmospheric turbulence. Experimental data, representing the disperison of tracers in the atmosphere, are examined in order to derive the values of the local turbulence parameters pertaining to the Hanford-67 (Nickola P. W., 1977) experiment. Once determined, these Lagrangian parameters allow for a renormalization of the lateral dispersion as a function of time, that exhibits data dispersion smaller by two to three orders of magnitude, as compared to that obtained by normalization through the use of corresponding Eulerian parameters. This closer packing of the experimental data allows for a more precise fitting of a theoretical curve that is basic to the determination of local Lagrangian velocity autocorrelation coefficients. The authors of this paper have agreed to not receive the proofs for correction.
