26 ! wbd,sbd and some other variables and 1D arrays.
27 ! - Note that in order to obtain coincident grid points, which
28 ! is a basic requirement for RSL, WRF infrastructure, we use
29 ! western and southern boundaries of nested domain (nest%wbd0
30 ! and nest%sbd0 derived from the parent domain. In this case
31 ! the nested domain may be considered as a part of the parent
32 ! domain with a higher resolution (telescoping ?).
33 ! - Also note that in this case, the central lat/lons for nested
34 ! domain should coincide with the central lat/lons of the parent,
35 ! although the nested domain NEED NOT be located at the center of
36 ! the domain.
