Re: [idvusers] HRRR fields coming up with errors

Mike,
We have a NCL script which also uses the HRRR via NOMADS/OpenDAP. The script is scheduled to run at :50 past each hour and use a run from 2 hours previous. We've sometimes seen intermittent behavior with similar types of errors where fields may be missing at certain hours. This can even vary when running manually, one minute the script works fine, running immediately after there is an issue. If I had to guess, I'd point to some sort of NOMADS issue, not sure who the POC would be to bring this up with.

I'm in the process of changing some of my scripts to point to the NCEP
version of the HRRR instead of the ESRL/GSD experimental version.  The only
place I've been able to find the NCEP HRRR is the NCEP NOMADS Data Server (
nomads.ncep.noaa.gov:9090/dods/thredds).  This also goes for the WRF-ARW
and WRF-NMMB.

Anyway, some of the fields from the HRRR model come up with an error and
cannot display, take 2000-5000m Hourly Max Updraft Helicity for example
(mxuphl5000_2000m).  Here are the details:

Can anyone else duplicate this?  HRRR model can be found navigating through
the catalog
Community IDV Catalog > Community Data Servers > NOAA NOMADS > NCEP NOMADS
Data Server > hrrr

Thanks,
Mike U
