Table 2. Semivariograms model parameters for the FULL data sets. Range is the range of spatial correlation, sill is the partial sill, RSV is the relative structural variability calculated where RSV = sill (sill + nugget)-1, and e indicates an exponential semivariogram model.  Min indicates minimum, max indicates maximum, s indicates the standard deviation, and CV indicates the coefficient of variation.
