Lake Arrowhead & Crestline Communities

the smog is accually "created" here, in the eastern end of the valley.

No way!

cindy_bo_bindy,

I am curious about this..

Years ago, the SCAQMD had released a report that in essence stated that smog in the East valley was significantly worse due to the westerly afternoon winds blowing the LA/Coastal smog over the Western part of San Bernardino and Riverside counties.

This was increase in smog was specific (at that time) to the smog passing over the high concentration of dairy farms. Not only were there high concentration of dairy farms, but inherent in that is high concentration of dairy cows and the resulting manure.

The report I read (at the time) stated that high concentration/decomposition of manure emitting methane combined with the dairy cow flatulence and other farming emissions significantly increased the smog levels for the eastern SB and Riverside valley areas due to the photo-chemical reaction resulting from this.

I am curious as to your insights whether this is still occurring given that there has been a subsequent migration of dairy farms from that area. Specifically Chino (you know the directions to Chino from Los Angeles... Go East till you smell it, South till you step in it).

Cindi, I believe that's what I said. Since the population centers are to the west, that's where the preponderance of precursors are formed, mainly from auto exhaust. By the time they blow out here with the prevailing winds the sunlight "cooks" them into ozone. Sorry if I was not clear, but I thought that's what I said. CPP has the most smog for the same reasons that it has the most snow. Microclimatic anomalies abound in this mysterious place. Also, there are naturally occurring bloviation anomalies producing large amounts of methane, which stinks but does not lead to ozone formation.

To say that inversion layers are "rare" is preposterous. Maybe the most truly uninformed thing you've ever said, at least that I've read on this site. Not you Cindi. What's his name.

LOL, my grandma lived in Chino years ago. I remember.
I'm not up on that particular study, however I am aware of the increase of Particulate Matter (PM10) pollution due to dairy farms. The manuer dries and is kicked up by the cow, or is picked up by the wind, dispersing it into the air. PM10 and PM2.5 are health hazards. The particulates lodge in the lungs causing damage.

Cindy,

I am glad my post made some sort of sense to you!

lol.. I read what I typed... Brain and fingers just not in sync

Thank you for responding

p.s. Chino has sure changed over the years, eh?

LTP,

That is an interesting link I was disappointed that the
Jane Strong's Visibility, Smog and the Inversion Layer in the San Gabriel Mountains
Link didn't work Were you able to get it? Would like to see it

Thanks!

"CPP has the most smog for the same reasons that it has the most snow. Microclimatic anomalies abound in this mysterious place. Also, there are naturally occurring bloviation anomalies producing large amounts of methane, which stinks but does not lead to ozone formation."

ROFLMAO!!!! I'm busting a gut here laughing so hard!!!

So that is where the smell comes from? I was never sure!
ROTFLMAO

Ok, sloppy terminology on my part. Substitute smog alerts for inversion layers and it will be more accurate and closer to what I intended to say. When I first became aware of severe smog as a kid, I could see the inversion layer with the brown sludge accumulated under it as a lense from my parents home in north San Bernardino. The number of alert days was in the hundreds in typical years. You could smell it, taste it and see it. In the past 2 decades we have experienced a significant reduction in smog alert days due to cleaner cars and reduction of some other sources of the most noxious gases and particulates. It is a rare occurance to see the same phenomena that I did as a kid with the trapped smog below an inversion layer. Yes they still occur but the intensity that is observable is relatively rare.

I have a much more positive outlook on the issue because the improvement has been obvious. And for those speculating about CPP, I am at 5200' and not in a bowl and do not get the same concentrations of noxious fumes as the Lake Gregory and Lake Arrowhead basins. I live near Breezy Point, which has enough air movement to make it seem like the air is always clean.

This is a reference to confirm my comments about the general improvement in our air quality over time.

I sure do remember those days in North San Bdno, Ron. In the mid sixties we lived on Elm and the Arden near the mountains. Most summer days my two girls couldn't play outside. I'd do yard work and nearly pass out from the smog and fear of black widow spiders that were everywhere. I think the house on Arden was on orange grove land. My older daughter had asthma which disappeared right away here. I began to have sieges of it as well. By '70 we knew we probably wouldn't live very long if we didn't get out. Even the dog got healthier.

We were neighbors Frankin. We were on Osbun Road. How come you never said Hi? Or did we date?

No, I am too old for you. I do like younger men however. Mark is four months younger than I. Besides, he was a Probation Officer and might have caused us trouble.

So was I but that was a few years later.
