What's that black dust in monitors?

Don Klipstein

You dont get that 'flowing out of some thunderstorms'

You sure as hell do; lightning is one source of the stuff!
Pity it doesnt end up brown at all at that concentration.


Yes, but not at 1 PPM it aint, even thru 4 miles of it.

Same amount of NO2 that light has to pass through!
Irrelevant to what air with 1 PPM looks like.


Thats utterly mangled too.

No, it's your knowledge of chemistry that is mangled.
And at 1 PPM it aint even visible.

Until you look through a couple miles of it.

"Brown Cloud" air pollution is nitrogen dioxide or nitrogen dioxide plus
carbon particles fine enough to make things seen through the cloud look
brownish due to scattering preferentially of blue light.

One source saying nitrogen dioxide plus fine carbon particles:
http://phoenix.about.com/library/weekly/uc051601a.htm

Another source saying nitrogen dioxide is responsible for "brown cloud"
urban air pollution:
http://phoenix.about.com/library/weekly/uc051601a.htm

Just the first two hits of a Google search of "brown cloud" "nitrogen
dioxide"! A few other hits whose summaries reported by Google appear to
support nitrogen dioxide, whether alone or with really fine carbon
particles, making air look brownish:

You dont see that rising either.

Are you calling me a liar? When it is visible, the finer stuff easily
visibly rises!
Dont believe it.

Looks like you haven't paid attention to a few on the road!
Thats just smoke, not the jet black soot being discussed.

So you say diesel trucks produce smoke other than soot and other than
the gray "oil burning" stuff? And what else has a "gray-transparent" look
when seen through and when finer, has a "diluted-milk-grayish-blue" but
darker when illuminated by sunlight?

I can make soot fine enough to look bluish when illuminated by a bright
flashlight by running a propane torch with the air intake holes blocked.
I just tried that! Are you going to say that propane can make ash or tar
particles?
Pity it aint the jet black soot being discussed.

"Brown Cloud" air pollution is nitrogen dioxide or nitrogen dioxide
Wrong.

plus carbon particles fine enough to make things seen through

Particles of many kinds, actually. Doesnt have to be carbon.

Its that that produces the spectacular red sunsets with major fires.
One source saying nitrogen dioxide plus fine carbon particles:
http://phoenix.about.com/library/weekly/uc051601a.htm

Its wrong. Basic physics. Steve clearly aint gotta clue and his
'credentials' are complete duds as far as physics is concerned.

Nope, just one actually. And plenty of pig ignorant shit turns up on the web.
A few other hits whose summaries reported by Google
appear to support nitrogen dioxide, whether alone or

We'll see.

The first para of that says

Extremely small particles are the principal cause of the brown cloud.
These tiny particles, too small to be seen without a microscope, are
measured in microns, with one micron equal to about one-seventieth
(1/70) of the diameter of a human hair. Particulate matter less than
2.5 microns, often referred to as PM2.5, is a significant cause of haze.
Each particle, about the size of a single grain of flour, can float in the
atmosphere for days, behaving much like a gas. Over half of the
PM2.5 in Phoenix is caused by the burning of gasoline and diesel fuel
in vehicles (sometimes referred to as on-road mobile sources) and in
off-road mobile sources, such as construction equipment like loaders
and bulldozers, locomotives, lawn mowers, leaf blowers, and other
devices that emit air pollution as they move1. PM2.5 particles containing
carbon, like soot from tail pipes, are particularly effective in reducing
visibility, because they both scatter and absorb light.

Which is exactly what I said, using a lot more words.

Doesnt say that the brown is primarily NOx

Doesnt say that the brown is primarily NOx

Pure political bullshit.

3. Is it a brown cloud day? A brown cloud appears to envelop
the scene but quickly thins out at higher elevations. Look at
the particle and black carbon levels -- they are usually high.
Ozone will be low and relative humidity may vary.

Doesnt say a damned thing about NOx
being the cause of a visible brown haze.

Try again.
Are you calling me a liar?

Nope, you just havent got a clue about the basics.
Those dont rise like say smoke from a fire does.
When it is visible, the finer stuff easily visibly rises!

Not far. THATS what matters.
Looks like you haven't paid attention to a few on the road!

Looks like you aint gotta clue about what's being
discussed, whether that stuff rises that much.
So you say diesel trucks produce smoke other than soot

A properly setup diesel engine does just that. Its only the badly
setup trucks that generate high levels of the jet black soot you
see inside monitors adjacent to the FBT, and as Ken pointed
out, you STILL get that inside monitors, even when there are
bugger all diesel trucks in use at all, let alone many setup
that badly. So it cant be coming from diesel trucks.

Basic logic.
and other than the gray "oil burning" stuff? And what
else has a "gray-transparent" look when seen through
and when finer, has a "diluted-milk-grayish-blue" but
darker when illuminated by sunlight?

What was being discussed was how many diesel trucks produce
much JET BLACK SOOT. You claimed that that somehow ends
up in monitors. You cant explain why you STILL get that jet black
soot in monitors even when there aint no diesel trucks in use at
all, SO IT CANT BE COMING FROM THEM.

Basic logic.
I can make soot fine enough to look bluish when illuminated by a bright
flashlight by running a propane torch with the air intake holes blocked.

Got SFA to do with whether the jet black soot you can see with
badly setup diesel engines is what ends up inside monitors.
I just tried that! Are you going to say that
propane can make ash or tar particles?

Nope. It doesnt produce JET BLACK SOOT normally
either unless you completely stuff up the gas to air mixture.

And that doesnt happen enough for it to be the
source of the jet black soot we see inside monitors.

They coexist in a ratio that varies with pressure, and nitrogen tetroxide

Nope, you just havent got a clue about the basics.

Not far. THATS what matters.

Tell me why and how you think fine soot does not rise the way other fine
dust does, especially given web pages giving a cause of "brown

carbon particles!
Looks like you aint gotta clue about what's being

I have been saying not-so-out-of-tune diesel engines produce finer soot,
as opposed to bad ones producing soot coarse enough to visibly fall out!
Or do you propose another source of carbom PM2.5 particles, which is a
primary alternative candidate to nitrogen dioxide for the "brown cloud"?
Nope. It doesnt produce JET BLACK SOOT normally
either unless you completely stuff up the gas to air mixture.

But I did stuff up the gas-to-air mixture, for the purpose of producing
soot particles fine enough to scatter blue light more than longer
wavelengths of visible light. And the soot was not always that fine but
sometimes it was, depending on how big the flame was and how completely I
blocked the air intakes.
And that doesnt happen enough for it to be the
source of the jet black soot we see inside monitors.

I did not claim that this was the case. My only claim related to abused
propane torches was that soot can be fine enough to preferentially scatter
blue light, not that propane torches, abused or otherwise, were normally
significant sources of what builds up in monitors and TV sets!

And this isnt 'brown clouds', this is right down on the horizon.

So when brownish air looks like the "usual brown cloud" but is less
opaque than usual but has the nitrogen dioxide brown color, you are going
to say it's not brown cloud and therefore nitrogen dioxide does not cause
visible air pollution?
And that stuff you see in Sydney is nothing like
'brownish but transparent air', its a nothing like
transparent smog/haze right down on the horizon.

And how does that disprove either sort of brownish air being tinted by
nitrogen dioxide, and how does that disprove presence of fine soot
particles in the air?
You dont get that either, and the PPM levels of NOx with
thunderstorms aint anything like that 1 PPM level anyway.

I did claim even less can make visible air coloration, and thunderstorms
are easily 4 miles wide.

When sometimes they are small enough to preferentially scatter blue
light?! Besides, when smoke reaches 1,000 feet or a few thousand feet
it's usually mainly for reasons other than heat from the source.
Even you must have noticed that brown aint jet black.

Of course a cloud of particles fine enough to preferentially scatter
blue light will look brown to transmitted light, but how does that make
carbon brown? Or are you now going to claim that carbon is brown?
DOESNT SAY THAT ITS THE JET BLACK SOOT
FROM BADLY SETUP DIESEL ENGINES THATS
THE SOURCE OF THOSE CARBON PARTICLES.

You seem to have this hangup on diesel engines setup badly enough to
make really coarse soot!

Only perfectly ideally, which many don't do! If .1% or ,01% of the
carbon becomes soot, that's not going to significantly impact fuel
economy!

Above you say:

That page says over half your favored PM2.5 is caused by gasoline and

If dust can come to Florida from the Sahara Desert enough to affect
air transparency, and if PM2.5 stays in the air for days, then how far
does a monitor need to be from sources of airborne carbon particles to
disprove the stuff being carbon?
Pacific islands, as Ken pointed out.



You're wrong.


There's plenty more combustion of carbon
based fuels than just diesel trucks.

So you propose gasoline, home heating oil and and natural gas being the
main cause of airborne carbon particles in "brown cloud"?
Thats just plain wrong too.
You cant explain why you STILL get that jet black soot
in monitors even when there aint no diesel trucks in use
at all, SO IT CANT BE COMING FROM THEM.

Basic logic.



All completely and utterly irrelevant to what happens much with
normal propane combustion, SO THAT CANT BE THE SOURCE
OF THE JET BLACK SOOT SEEN IN MONITORS EITHER.

So it was completely irrelevant waffle, just like the 'brown clouds' are
in spades.
