Hi Roy:
The grids look ok (L3m), although they didnt put the time values into a
coordinate, but in global attributes.
The swaths (L2) can probably be fixed up with a little NcML. Its not clear
if aggregation is possible or useful.
The points (L3b) are incomprehensible to me. Someone expert would have to
explain whats in there.
Not a lot of CF compliance that I can see.
