[CF-metadata] [Fwd: representing multiple nests]

[Jonathan Gregory]

Dear John

There is no explicitly stated way to represent nested grids. Of course, any
grid, however constructed, can be recorded by regarding its coordinates as
1D lists, with no knowledge of the structure of the grid. This should always
be done anyway. The issue is how to record the "higher-level" information
about its construction. It's similar to the issue of relating u and T grids.

Perhaps Balaji's proposal at the GO-ESSP meeting would help with this too. I
believe he intends to propose it to CF.

Best wishes

Jonathan
