Re: [idvusers] HRRR fields coming up with errors

daryl:  I was not aware of that data source, although it looks like the
grib2 files are separated out for each forecast hour, which isn't all that
convenient for loading in to IDV.  The link you provided is the sub-hourly
HRRR (15-minute forecast intervals) anyway, which only have a limited
number of fields.

Brendon:  Thanks for the feedback.  The field in question (2-5km Hourly Max
Updraft Helicity) never works, regardless of forecast hour.  The data is
there, and the IDV is downloading the subsetted grid, but when it's done
loading and ready to display, IDV returns the error.  Most of the fields,
however, display properly, it's just a couple fields that come up with
errors.
