Re: VIIRS SNPP polar_wander.ascii update is broken

I notified the web admins about the cached invalid file.
If they don't get it cleared today, it will be replaced with a good copy overnight.

Re: VIIRS SNPP polar_wander.ascii update is broken

The server where we retrieve the polar wander data was serving out HTML error files yesterday. It was fixed later in the day.
Can you run the command with -d and see what location it is pulling the files from? It looks to be caching the bad file.

There was a processing backlog over the weekend and those granules have not yet been created. They should be available later this morning.

Question: SeaDAS 10.0 Windows fails to open GOCI L1B (NASA source)
Replies: 2

Re: SeaDAS 10.0 Windows fails to open GOCI L1B (NASA source)

The GOCI L1B data are stored as compressed files on our archive, but when you download it, the downloaded file will not have the compression suffix. (gz or zip)

Try running the file command on the L1B file to ensure it is not compressed.
