I just saw that in the data assimilation flag WC13, there is a cpp definition #SPHERICAL turned on.
In cppdefs it mentions "use if analytical spherical grid".
Obviously it's nothing associated with the flag spherical in the grid file,
which is a flag for if it's in realistic lon,lat coordinate or not.
Anyone could suggest when we should define this in cpp?
