[Datastream #DEJ-475879]: plea for Nexrad III help

OK, MRMS is GRIB..WSR-88D is not.

 I used the NOAA wct Climate tool to convert the polar spheroid 5 minute scans 
to ASCII, then ASCII to our gridded format.

MRMS may be your best bet here.

There are Z-R algorithms available via regions and seasons from U of Iowa and 
others, but this is computationally heavy.

U of Iowa IIHR did precisely this task via the Hydro-NEXRAD project of 
2009-2011. They ~might be a good resource as well for this task.

  We need an even interval product that can be ingested in under an hour.

For this task I would pursue MRMS.
