VIIRS subscriptions not updated

Hi,

I have several VIIRS-SNPP and MODIS-AQUA subscriptions. The MODA seems fine, but the VIIRS subscriptions have stopped updating on 7/9 for OC and on 7/10 for nighttime SST.

Thanks,

Dan

The GPS on SNPP stopped functioning so there are no accurate geolocation data. VIIRS processing was halted until the GPS is reactivated.

You should see some new data this evening.

Is the missing data from July 10-15 definitely lost or will it be recovered later?
Thanks,
Julien

I would assume lost. With SNPP being the tertiary platform, I don't expect much effort to recover the data.

SNPP VIIRS processing is paused again. The GPS is not stable. There are no plans on recovery before next week.

Just got word that the GPS was successfully synchronized by the vendor at 2024-07-16 17:42 Processing has resumed from then
