    710 A value for this parameter must be assigned. Since the lower array bound in PALM starts with k = 0 and since one additional grid point is added at the top boundary (k = '''nz+1'''), the actual number of grid points is '''nz+2'''. However, the prognostic equations are only solved up to '''nz''' (u, v) or up to '''nz-1''' (w, scalar quantities). The top boundary for u and v is at k = '''nz+1''' (u, v) while at k = '''nz''' for all other quantities.\\\\

    711711For parallel runs '''nz''' must be an integral multiple of the number of processors in x-direction (due to data transposition restrictions).
