! There are four subgrids, labeled T (for tracer), C (corner of T), N (north of T)
! and E (east of T). The following schematic describes the grid cell notation.

! The grid_spec file would contains all of the following information.
!
!
! x_T, y_T = Geographic location of T-cell center
! x_vert_T, y_vert_T = Geographic location of T-cell vertices(each cell has 4 vertices)
! x_C, y_C = Geographic location of C-cell center
