I’m pretty sure everyone has noticed the smoke by now. It’s not actually that bad near the surface, but once you get higher, sort of mid to upper troposphere higher, there is a think shroud of smoke. Once again, it’s not that bad, I can still see blue sky until about 35 degrees off the horizon, so it’s actually more like a haze. If the smoke was the same density all the way through the atmosphere, I could use a little math to figure out how far up it goes.
I did. It took a whole hour. I started at 10 and now it’s 11. The result was ~9.5 km, which would take us to almost the tropopause.
This smoke was un expected because I thought a forming high in southern Alberta would keep it all to the north. The thing is, a mini-high decided to also form, this time in northern Alberta. This one was just in the right position to push enough air down to give us some smoke. I’m still waiting for the latest maps, but at the moment it looks like the smoke came in at about 5 am, followed by low levels of smoke until about 8 am, before moving off to the east. The stuff that we can see right now is just the non-lower-troposphere smoke, and a little leftover haze.
