Carbon monoxide from the fires very visible right now on Windy: https://www.windy.com/-CO-concentration-cosc?cosc,-16.636,13...

And what's up with Belgium? Appears to be a huge plume from Dunkirk.
Yeah its NASA's MOPITT sensor on the Terra satellite

I’m looking out my window in the South Island of NZ and the morning light is an unusual, deep yellow.
News said there’s high-altitude smoke from the Aussie fires overhead today and this light suggests it’s already off to the east, but that’s not borne out on that neat visual.
Seriously, though, I'm genuinely curious as to the real answer. Any ideas?
But in this particular instance, it’s hard to be sure if that’s the explanation without knowing more. The data will only be observed once or twice per day, due to the MODIS orbit, and clouds and other problems will cause dropouts. These website data seem to be interpolated spatially and temporally using wind fields and perhaps other side information. So these areas of apparent high CO concentration could be due to the transport model or the prior as much as the actual observed CO data.
The website doesn’t say what data product they are using. The MOPITT website advertises daily data, but the displayed data are faster than that.
Windy also has an "Active fires" layer: https://www.windy.com/-Show---add-more-layers/overlays?fires...
(but the pollution layers are often more fun, and more revealing)
which I think is data from Copernicus, but I'm not sure what the data is exactly.
The African ones probably are probably mines too.
