[THREDDS #EBO-191519]: Doppler radar data request...

Greetings,

Our THREDDS catalogs only store one month's worth of NEXRAD data, so I 
apologize but I don't think you'll be able to find what you need there anymore.

Normally for longer term NEXRAD data I recommend NCEI, but you said you already 
tried that.  After taking a look I see what you mean, large chunks of time 
where nothing is available for that site.

After taking a look at that data and those dates I have a theory:  I didn't 
find any notice from that NWS office regarding an outage, rather I saw notices 
that showed the radar was operating.  But since this was during Hurricane Ian, 
it's not unlikely that some infrastructure in the area was out of service for a 
time, so maybe transmitting that radar data out of the office wasn't possible 
periodically; that would explain the large data gaps.

There's another place I can think of you could try, the Google Cloud Nexrad L3 
historical archive:  
https://console.cloud.google.com/marketplace/details/noaa-public/nexrad-l3

Unfortunately, glancing at the file sizes of the data they have for that site 
and dates, I suspect similar gaps will appear in that data as well.  If true 
this would further support the theory that data was somehow unable to make it 
out of that office for a time if no archive has it.

The last thing I would suggest is to reach out to that office to see if they 
have another source or archive for that data.  Their web page is here 
(https://www.weather.gov/ilm/) and there is contact info on that page.

Sorry I wasn't able to give you better news but I hope this helps.

Best,
-Mike
