The Science Behind Wildfire Smoke

And when they die down, that's actually when they produce quite a bit of smoke. And that mixing into a more shallow boundary layer just means you get a lot more smoke very close to the ground, particularly at night.

especially if you're in a kind of a mountain valley where it just starts to pool and accumulate and it's not really diluted or moved out of your immediate area until the sunrise comes, that boundary layer starts to expand, the wind speeds pick up and kind of Sure.

It is, yeah, and that's true of most air pollution sources, but particularly so for smoke. In many of the western states, even here in Colorado, it's not necessarily all that common that you have air conditioning. It does cool down quite a bit at night, and so that is the time people would turn on fans. etc. to try to ventilate the house, get it cool at night.

Of course, you're home at night sleeping and breathing all through the night. And so again, that's one way that you can be exposed to smoke that you might not necessarily think of.

Certain smoke plumes can literally travel the world and go to really, really remote places. Wow. And of course, with fires, you know, we're impacted here in the United States right now. But of course, that flips as we go to the next season and then the southern hemisphere. So fire is just a constant emission source, you know, across the globe.

And as I said, as it gets emitted into the different layers of the atmosphere, it can stay in the atmosphere longer. And that just means it can get carried by the wind currents further and further downwind. And so that smoke can just travel. tens to hundreds of miles downwind from the source. Yeah, yeah.

The primary component is going to be related to those particles. And so particles are something that can both cool the climate as well as heat the Earth. And so that's where that size and color of the particles really comes into play. And so the white particles. Particles that you associate with clouds generally reflect radiation back to space, so that's a cooling effect, right?

If you're under a cloud on a super sunny day, you immediately feel better and cooler when that cloud is overhead. The other way is that those darker particles, the black soot, those are things that readily absorb radiation from the sun, which means when the sun goes down, they can also readmit radiation. that radiation back into our atmosphere.
