The grid descriptor, DIJK, consists of four integers. The first indicates the dimensionality ("D") of the field (2-D or 3-D). The three integers which follow identify the i,j,k-grid upon which the field resides, where a value of "1" specifies the tracer grid and a value of "2" specifies the staggered velocity grid.
