Steve,
You don't quite understand the notation. I think what you are looking for is
[a.x, a.y, a.z*b/22].
The input for b is the marked data component for temp. Since your
grid is the same for both, then the order at which the data is stored
is the same (typically). So when dx starts doing its calculations in
row order then the a.z and temp should be at the same position on the
grid.
With that calculation, you then Unmark back to positions (now in 3d)
and then use a Shade module (to help show the relief). However, a lot
of times with visualizations, you may have to scale your Z to make it
even look good which is what Rubbersheet does.

So I'm guessing that I'd use Make3DField then to add a third dimension?
I'm finding no documentation of Make3DField. Has anybody used this to
create a 3D array out of a 2D array where each vertical slice (Dimension
Z) is a copy of the original 2D array? I see the Stack module and I've
given it a try too but it isn't cooperating (or I guess I'm not). I
can't see where to tell it that I want the 3rd dimension to have 22
levels.
What I want is to multiply a(x,y,z) by b(x,y) where b(x,y) is the depth
at grid point (x,y). It really isn't a vector so I don't think mag()
applies. I think that if I can construct a 3D version of the depth
array then I'd just do:
[a.x, a.y, a.z * b.z / 22 ]
Thanks very much for your help,
Regards,
Steve
