A neat perk of iOS/watchOS 12 is that it now supports Air Quality in the Weather app/Siri, which has been very useful over the past few days!

Why is it useful? What do you do about it?

It can be useful if you need to make a decision on how active to be outside. It’s usually not a good idea to be running/cycling (for fitness) or other similar activities outside with very poor air quality.

However the masks worn on the streets in Asia don’t do anything to stop the 2.5 particulates.

Incorrect. A mask rated N95 filters out more than 95% of particles (PM) larger than 0.3 microns — that’s much smaller even than PM2.5 microns. Certified 3M N95 rated masks are sold all over China.

The question is how much air bypasses the masks at the sides. The holes there are huge and any air that passes there will basically have the full smaller particle load. Do the masks produce considerably more resistance to breathing if you press them on with your hands? That would be a sign of this happening.

If interested, here is a link to the air quality index, as measured by purple air monitors: https://www.purpleair.com/map#11/34.0244/-118.4531 The map extends worldwide, but only reports data from those who have purchased their monitors.

I'm quite concerned about air quality in the UK but according to that map everywhere in the UK is "good", even London.

They only seem to take aerosol into account. And if you're looking at the current data, that's a saturday morning, which most properly means the traffic is pretty low.

So if the air quality is bad, you'll drive. I see, very useful.

A few days ago it smelled and looked like smoke in San Francisco. A “Hey Siri, air quality” into the Watch returned “Unhealthy.”

So you don't trust your own eyes and nose and need "Siri" to confirm it for you?

Or not run outside. Or if I cycle, not press hard.

Truck traffic in LA is by far the problem, not so much the car traffic (though that is horrible, based on the population). Ships come into Long Beach, the containers are offloaded, the trucks begin a lumbering journey to points East. Belching all the way. I'm not making up the claim. California rules put in place over ten years ago had trucks retrofitted or whatever, and this change to TRUCKS ONLY was like removing 3…

I got on the 710 once heading south and it was a whole different world in which it felt like there was an unbreakable chain of trucks. It also felt extremely dangerous since they really didn't care about breaking that chain to let you into a lane if you needed to exit.

Once was enough.

I’m not a climatologist.

Can anyone summarise the article for those of us in Europe? We can't get the LA Times here. What has changed this year - wild fires? Or is it the problem of ten million cars pissing in the pool with no wind to clear the air. Do tell.

I’d do just that but I’m not sure if it’s legal in Europe either ;) Jokes, full article: https://outline.com/CrmCSK

That's a useful site. It reduces the Daily Fail to a single paragraph!
