Hi Bill,

Not all of the NetCdf attributes are available through the current Ferret
interface. The Users Gulde section on labels tells you which ones are --
basically "units" and "longname" and the missing value flags. They are
available through the automatically generated plot labels -- see the UG
sections on "Symbols".

In your example, the global attribute "location" will not be available directly
through Ferret ... though, you can use Unix commands in your Ferret script such
as:

    sp ncdump -h file.nc | sed 's/location/LABEL 1.0,1.0,0, 0, 0.1 /' >
cmnd.jnl
    GO cmnd
