Click on "Research and Reports" on either of the American Lung Association links (embedded link in the LAT article). No, it isn't good news for California.

If it's not 2023 data or newer I don't care about it. That's old news.

When I was a school age kid in the 1960s living in the SF Bay Area of northern California, I often spent a month during summer at my grandmother's house in San Bernardino (Inland Empire) in southern CA. Although the smog is still bad in San Bernardino and Inland Empire, it was no doubt much worse 50-60 years ago. I would often get a headache and remember washing windows on the outside of her house, and seeing the black grit that would collect in just a few weeks. The smog was so bad on some days that a neighbor used to say that you need to chew the air as your breathe.

Unleaded gas, lower vehicle emissions and industrial pollution limits have helped a lot. It doesn't happen overnight, but over a long term significant progress has been made. The same can probably be said for the majority of metro areas in the USA.

Yes, we were pulled off the playground for third stage smog alerts through the early 1970s in the suburbs of Los Angeles. Things have certainly improved since then.

That doesn't mean they're using 2023 data!
One NEW article showed data for 2020-2022 only. Article came out like a week ago.

They're using the most current data available. Download the report and read it yourself. "Year-round particle pollution. Design values for the annual PM2.5 concentrations by county for the period 2020-2022 were retrieved December 18, 2023 from data posted on May 23, 2023, at the U.S. Environmental Protection Agency’s website..." I don't see any stats at all for your Bloomingtonian report.

Your link specifically states the data from 2020-2022. OP's link specifically states pulled from EPA monitors for 2023 and looks to be pulled from EPA's Outdoor Air Quality Data site which is constantly updated and does have 2023 data. The methodologies probably differ, but I think it's important to note that 2020 and 2021 had millions of acres burned while 2022 and 2023 had hundreds of thousands of acres burned with the latter being much further out from major metropolitan areas, so that order of magnitude difference for the first two years of 2020-2022 probably heavily stack it against 2023 data for either methodology. Note that 2023 did have several notable fires in the Inland Empire so that probably didn't help.

California did get some nice last and current water years so that's pretty neat. I think one question is how has forest management and fire fighting and prevention evolved in that time period. Anyhow, in comparison to a place like Houston where massive fires aren't quite as common as the area gets quite a bit of precipitation and there's no basin in Houston to hold in the pollutants. It's further north and west in Texas where they can get large wildfires, so likely this means that Houston's more localized industrial and man-made emissions are much more likely to be the primary causes.
