Dear Thomas

I think it may not be explicitly written down in the CF standard, but it is
certainly assumed that the coordinates you give (xc yc) are the gridpoints.
For an intensive quantity, the default interpretation of the data is that
it exists at particular points, which are those specified by the coordinates.
Your application is making a surprising assumption in taking the coordinates
to lie at the corner of the cell. As you say, CF provides bounds in order to
describe cells, because that's not what coordinates are intended for.

Cheers

Jonathan
