Thank you for pointing this out, as it appears to be exactly what I was looking for. -- Grant On Sun, Jul 26, 2020 at 8:15 PM Ryan May <rmay@xxxxxxxx> wrote: > 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.
