Actually there is a site (iqair.com) that estimates air quality in Zihuatanejo based on the latest satellite data for particulate matter.

Sounds like a lot of guesswork. And look. It appears to confirm that the air is fairly stagnant and there are no air monitors along our coast or even in the state of Guerrero.

In LaRopa and must just be the crappy neighborhood. The sunset with no clouds is as red as it can be which indicates sample. Maybe we are just sensitive to it but yes we can smell it and feel it in the eyes and breathing. I looked up some area air quality and the problem is in and down the coast. 115 to 136ppm.

Air quality? You mean as if there were measuring devices capable of sampling the air quality up and down the coast of Guerrero? Excuse me while I have an uncontrollable bout of laughter...

While certainly some folks may be trying to burn some of the debris from Huracán Rick, and there are others who burn their trash because they're too lazy to dispose of it properly, in La Ropa the only smoke you're likely to encounter comes from local restaurants, especially those that use leña for cooking with.

As wind circulation increases and cold fronts move through the haze will decrease, like this morning which was cool (for us) and especially clear and cloudless.

Note sample, Smoke

No one can sell me on this is a Marine Layer. BS. This is nasty smoke. I can smell it, I can feel it and my eyes are irritated. The DUMP is on FIRE. Most likely there is a majority of organic material from the storm. That material is still wet and will burn very slowly. This is LA in the 70's. Not a Chamber of Commerce Sunset.

I don't smell anything out of the ordinary. Pretty sure our little dump wouldn't affect visibility for kilometers in all directions, though the dump may be on fire (no me consta). Do you live near the dump? See any smoke? This haze occurs every year at this time of year. I even posted a photo recently taken at this time of year from a few years ago and it looks exactly the same as it does now.

There has been a huge amount of burning, possibly a lot of the debris from the hurricane.

I'm pretty sure we'd smell it if it were smoke. We call haze bruma, and I suspect it has to do with changing sea temps (cooler currents are close by), humidity and the lack of any real breeze. However, the residents in Petacalco have been complaining about pollution from the thermoelectric power plant, so it could be a combination of the two.
