    • In most of today's LES computations, the filtering operation is basically implicit. This means that the process of numerical discretization (of grid size A) in itself creates the filtering effect. Although explicit filtering of the grid-resolved velocity field is desirable from a theoretical point of view, limited computational resources make it impractical [25] . However, in a priori studies of DNS, experimental, or field observations, where fine resolution velocity fields are readily available, the explicit filtering (typically with a top hat, Gaussian or cutoff filter) followed by downsampling is usually performed to compute the resolved (and filtered) velocity ūi. This issue of filtering of velocity fields should not be confused with the explicit filterings done in the cases of similarity, dynamic, fractal, or multiaffine models to compute the SGS stresses or other necessary SGS tensors.

    • Following [34], this filtering followed by downsampling methodology is known in the literature as "consistent" a priori analysis.
