Re: [ldm-users] The end of NOAAport, the "cloud", and UNIDATA

Hi Gilbert and everyone,

I too would like to hear from Unidata on this front.

We've known the tentative end of NOAAPort/SBN has been coming for a while
in the form of the Raytheon contract ending right about that same time,
fall 2027.  NWS is moving AWIPS into the cloud, as such will not need the
SBN for WFOs anymore after that.  Last I heard there is no on-ramp for
partners into their cloud system, and I _believe_ the _hope_ was it would
still stick around for another couple of years...  but I have yet to hear
any sort of mechanism for how that would actually continue.

The best thing you and others in your position can do now is prepare and
plan ahead for contingencies.  Where else can you get data from?  Using
your NEXRAD2 example, that data is available on AWS, so is NEXRAD3, both
managed by Unidata in fact: https://registry.opendata.aws/noaa-nexrad/  As
for other data, here's a solid place to start:
https://www.noaa.gov/nodd/datasets

Actually, if any NWS/NOAA/NODD folks are on here (hello), is there any
intel on this front that you could share?  We would all greatly appreciate
it I am sure.

Hope everyone is doing well!

Best,
-Mike
