I think it would need to be reasonably clear what the contents of this variable should be in order for it to be useful as a standard (and it's more metadata than a data variable, so I think it may be better just to improve the cell bounds part of CF). It'd also be good to be clear how this differs from and is better than the cell boundaries. I think you mean a standard way to specify that a pixel is "100m horizontally" rather than "drawing" these with vertices in a bounds variable? Perhaps you could expand on this? Cheers, Mike.
