Re: Mass Transport
Use xbox and zbox:
let meri_transp_box = v*xbox*zbox
If your grid is geographical then this will be transport across each
gridbox of your section in units of m3/s.
A test is whether meri_transp_box[x=@sum,z=@sum] equals the total
you found by your original method.

I tried to associate the @din function with other (@shf) but doesn't work.
