Hey everyone, COD has some glitched imagery on their site and I believe the source is the SBN data. Here is an example (maps are missing and that's okay): https://weather.cod.edu/data/satellite/global/halfdiskeastnorth/02/halfdiskeastnorth.02.20240819.110522.jpg That's Full Disk data from SBN, and that's the only place I see this sort of thing occurring; not CONUS and not West, only East FD. It's not ALL the time, but it's enough to notice especially when you realize some frames are missing entirely. When I plot the same data from GRB the image appears normal. I can recreate this in McIDAS pointing towards Unidata's ADDE so it's not just COD. The other thing I noticed, if you look at the timestamp that's at minute :05, which is outside the normal 10-minute cadence. When I look at the metadata via McIDAS that was in Mode-4 (5-min FD) whereas normally it's Mode-6 (10-min FD). A few frames later it's back to Mode-6. I suspect somebody upstream is aware already. There are a few notices about degraded GOES-16 data here ( https://www.ospo.noaa.gov/operations/messages.html) but nothing that's current. But given they're changing the satellite mode I have to assume that's done intentionally. I believe Gilbert is reaching out to OSPO separately, but I wanted to pass this along here too.
