Major Problem With NWS Satellite Data Continues
Weather Service stops receiving satellite data, issues notice about forecast quality, Washington Post
“Since at least Tuesday, some satellite data – an important input to weather prediction models – has stopped flowing into the National Weather Service due to an apparent network outage.”
National Weather Service National Center for Environmental Prediction (NCEP) Satellite Data Outage
“THE FOLLOWING DATA TYPES CONTINUE TO BE UNAVAILABLE FOR THE MODELS.
MODIS IR AND WV WINDS
OMI OZONE DATA
AIRS HYPERSPECTRAL SOUNDER DATA
COSMIC GPS-RADIO OCCULTATION DATA
NESDIS CONTINUES TO WORK ON RESTORING ALL THEIR SATELLITE DATA PRODUCTS.
IT IS DIFFICULT TO ESTIMATE THE EXACT IMPACT OF THE SATELLITE DATA OUTAGE ON NUMERICAL GUIDANCE AT THIS TIME. BUT THE DEGRADATION OF THE MODELS INCREASES WITH AN EXTENDED OUTAGE.”
It’s not the satellites, both GOES east and west are still producing images as well as the other birds…
That implies that there’s a problem upstream of the ground stations.
If the raw data is still available from their digital recorders (read: they haven’t wiped over the tapes yet), they should be able to do tape playbacks and reprocess the data through the ground station’s telemetry processors.
Yes, the articles are murky as hell.
Read the post. No one claimed that there is a problem with the satellites – just the collection of the data.
Even that could imply something worse that it is. Technically, the data are being collected. The spacecraft are correctly turning photons into data numbers and recording them. It sounds like the data are also being correctly sent down to Earth. The problem seems to be a serious glitch in the ground data system’s ability to transfer the data to an end user.
That might sound like nit picking. But I work with planetary missions, and we make a big distinction between data collection (which is done on spacecraft, sometimes days before the data gets sent down and reaches the uses) and ground data flow. Using the phrase “problem with… data collection” technically implies a flight anomaly, which would be alarming but isn’t correct in this case.

Yea that is what has been bothering me in seeing this headline (its not Keith, its everywhere) as everyone does think there is a problem with the birds.
What is incorrect about my headline “Major Problem With NWS Satellite Data Continues”?
It kind of sounds like it’s bad data, like we’re getting bad data somehow, which implies the satellites. That’s just how it sounds to me if you just say data as opposed to data collection or data handling. Problem “with” the data is different than problem “in” the data, and your headline is fine there, just perception issue I guess.
The headline is “problems with … data continue“
not “problems with … data collection“.
That’s right. But I was quoting Keith’s comment, not the headline.
I you are sitting on the east coast of Florida, at least some of this data could become mighty timely, and soon…
NESDIS computers were hacked and NOAA does not want it out. This is beyond conjecture, but that is all I am going to say.
