[CF-metadata] cf_role attribute

Hi Ajay,

In your netcdf file is *station_name* identified as an aux coordinate
variable by listing it in the *coordinates* attribute?

There is a mistake in the H2 example (and others) where *station_name*
should be identified as a aux coord var on the *coordinates* attribute
for humidity

I raised this and other defects in ticket 103 -
http://kitt.llnl.gov/trac/ticket/103

Hope this helps,
Regards,
Ros.
