Dear Glenn
The positive attribute hasn't been extended to data variables in CF because
the standard name always implies the sign convention e.g.

The advantage of doing it is this way is that it is impossible for the sign
convention t
it correctly stated. What kind of questions were

Since the variable really is representing pressure, not depth of water, I think
it's safe to say that increasing values of course represent in
