Re: Satellite imagery broken.

Thanks again for all the effort here, I understand when using outside data sources things change, and it’s a struggle to always keep up...

I’d written before that the imagery in the Northern Hemisphere west of about 1yºW seems to not update as I believe it had been - scrolling through the data, it still seems to that about 20-25 minutes before “now” there are no updates. Previously, there was a contrast at that longitude with the imagery to the east, which did update until the present minute.

I’ve noticed today that that now none of this imagery seems to update more recently than that same 20-25 minutes. Also, perhaps related, the eastern images seem to be missing a layer; the resolution over Europe seems markedly lacking due to that west of the line. I would conjecture that there is a problem with the pipeline and/or possibly an outage of the data feed on the east side as well.

I understand the challenges, as I said. I’d very much appreciate knowing whether I am misinterpreting this, or whether it’s a known problem. I do also understand you may not be able to fix everything, but I’d feel better knowing if “it’s just me”.

Thanks, again!

@idefix37 Ha! Thank you - that makes things a bit more clear...

I think that 16°W boundary might be explained by that reference, it seemed like this was probably based on a particular satellite view.

I’m not sure the data questions are, though.

What I see over the last 36 hours or so is that the data for my region (visible, 42°N, 72°W) seems now just to not be current, consistently 25-30m ago the animation “freezes”. So now that I know you have a data pipeline doing some rather intensive processing of the data, I wonder if it’s “behind”? I also noticed an update a few minutes ago while looking at the page, and it appeared that it may have been another frame, but stamped still from about half an hour ago. I wonder if something is happening to exceed processing resources, or you’re still catching up from some point over the weekend, or a node offline, etc.

By the way, that reference was to interpolation of the imagery - I does seem to be updated every minute, so I assume that enhancement was released for mobile (at least, iOS), and many thanks for that!

Just to be clear: I assume the satellites are geosynchronous - or is there timing to grab or compute a consistent perspective from several of them? Also, I’m wondering if I see what seems to be an illusion of a z-axis, or whether I actually am able to discern different layers of clouds? It must be that the resolution is very high, or maybe a side-effect of the interpolation?

Very much appreciate the info! Thanks for everything!

@idefix37 thanks! Not sure you made any changes... but it’s mostly working again.

Not entirely, though - it still seems to have some gaps. Nothing like a few hours, and maybe those have always been there and I just hadn’t noticed.

I also have to point out that I wouldn’t be focused on the imagery if it weren’t so beautiful. This data source is amazing.

Looks like it came to life again at around 1330Z until 1510Z. Maybe something “stuck” somewhere....

Any ideas here? Looks like west of about 16W long. stopped being updated around 0400 UTC?

Thanks!
