The old code has zcorl(ji,jj) = zmass(ji,jj) * fcor(ji,jj) which seems reasonable from a B-grid perspective (U/V collocated) but the new code has zcorl(ji,jj) = zmass(ji,jj) & & *( fcor(ji,jj ) * wght(ji,jj,2,2) + fcor(ji-1,jj )*wght(ji,jj,1,2) & & + fcor(ji,jj-1) * wght(ji,jj,2,1) + fcor(ji-1,jj-1)*wght(ji,jj,1,1) ) * zusw which seems to be C-grid. However, LIM2 is still B-grid right?" Bug closed low LIM2 v3.2 invalid LIM* v3.2
