The problem is that these are ill formatted data files, particularly with 
regard to units.  Thus, the IDV is looking for the location information, but 
can't find it because the altitude has units of:

        float alt ;
                alt:long_name = "Site Altitude" ;
                alt:units = "Meters, ASL" ;

and it should be:

        float alt ;
                alt:long_name = "Site Altitude" ;
                alt:units = "meters" ;

to be udunits compatible.

In general, the EOL Profiler Data Source was a hack, so  I'm not surprised it 
doesn't work.  It would be good to work with EOL to fix some of the issues with 
the profiler formats and perhaps move to a more widely used standard like CF 
conventions.
