Hi Grant,

On the AWS listing for NEXRAD data:

  https://registry.opendata.aws/noaa-nexrad/

You can see the listing for the `arn:aws:s3:::unidata-nexrad-level2-chunks`
S3 bucket. This bucket contains a freely available, real-time feed of the
individual chunks of Level 2 NEXRAD data (that once assembled form a full
volume). This is the lowest possible latency you have to the data, unless
you're upstream of us. On that page you'll also see a listing for an SNS
topic that will notify you when new chunks are available.

Both real-time chunks and full NEXRAD level 2 volumes are available on AWS
without a paywall--I'm not sure why you'd characterize it as "hard to
access outside of private vendors/paywalls".
