  The hypothesis of self-organized criticality explains the existence of
long-range `space-time' correlations, observed inseparably in many natural
dynamical systems. A simple link between these correlations is yet unclear,
particularly in fluctuations at `external drive' time scales. As an example, we
consider a class of sandpile models displaying non-trivial correlations.
Employing the scaling methods, we demonstrate the computation of spatial
correlation by establishing a link between local and global temporal
correlations.
