Thank you Ryan.
I have been using the AWS bucket to access the full volume archived data
https://s3.amazonaws.com/noaa-nexrad-level2/index.html
I was unaware there was a real-time feed as well, transmitting the
individual chunks. Thank you for pointing this out, as it appears to be
exactly what I was looking for.
