[Datastream #SWJ-684609]: Accessing NEXRAD Level 3 data

Hi,

If you're looking for Level 3 data going back that far NCEI might be your best 
bet.  But if the Level 2 data on AWS suites your workflow better it sounds like 
you've got a plan.

Regarding N0Q vs. N0B, the NWS transitioned away from N0Q to N0B earlier this 
year.  N0B products are known as Super-Res because of their increased spatial 
resolution, and around February sites began to switch over so you may run into 
this on other data sources.  For more information see this Service Change 
Notice describing the changeover:

Best,
-Mike
