"STEADHAM'S STUDIES
If they are really interested in measuring the effects of various aerial activities on cloud cover, NASA wizards ought to contact Mark Steadham."


Before we go any further, I think you chould contact Mr. Steadham and ask him just whom it was that he released his study to before he published it on his website in 2001. Ironically enough, Steadham's first reviewer read the entire document on a laptop on Delta flight 48 from LAX to Tokyo Narita, at 32,000 feet, probably spraying "chem-trails" as he did so!

"To plumb the mystery plumes, the previous winter Steadham correlated 46 personal observations of jet traffic over Houston with airliner identification provided by a computer program called “Flight Explorer”."

And this is exactly the same program I have been talking about to people who pretend to be researchers. And guess who it was that turned me on to it?

Yes! Mark Steadham!

"This consumer software also uses “real time” FAA tracking to plot commercial flight paths across the USA. It does not track military flights, which are identified only as unidentified aircraft."

"After using “Flight Explorer” to identify the airliners and military aircraft passing overhead, Steadham timed their respective plumes. Some examples tell this chem tale:"


Rather than cherry-pick, joepits, why don't you publish Mark's site so that we can see the entire report? It turns out that there were just as many persistent contrails from identified aircraft (i.e., civilian ones0 as there were from unidentified ones (i.e., military ones).

You do have the link to the original report, don't you?

"Steadham also found:
All confirmed contrails lasting 15 seconds or less: 72%
All confirmed contrails lasting 30 seconds or less: 80%
All confirmed contrails lasting 2 minutes or less: 96%"


And how do you define "confirmed contrails", joepits? By the fact that they dissipated?

If that's the case, then you're saying is "we know that these are 'confirmed' contrails because they dissipated. And look! All the 'confirmed' contrails dissipated!"

That's what scientists call "circular logic", joepits.

Now why don't you get the link (which, of course, you have, right?) to Mark's report and publish it for all to look at.

And, since you've already taken two semesters each of engineering physics and engineering chemistry, we can do a quick statistical analysis (you can do that, right?) to come up with a correlative for persistence and identification type.

Hey, Joe. Go over to Mark Steadham’s (Thermit) site and dig around in the forum archives. If Mech hasn’t deleted them, try and find any posts by “canex” or even by “dogbreath” (an earlier screen name). Although he never officially confirmed it, Canex is widely acknowledged to be the NASA Wizard himself, Patrick Mimus.

While we are on the subject of Mark Steadham, if you frequent his site, you may notice that he rarely posts on his forum anymore and has turned over the majority of the forum administrative duties to Mech. In one of his posts about a year back, Steadham (thermit) acknowledged that persistent contrails exists.

And as for this statement:

According to the latest atmospheric research, that is not true.

“There is now plenty of evidence that ice-supersaturation is frequent in upper tropospheric clear air and that it does even occur in the lowermost stratosphere. . . .
Additionally, laboratory work on homogeneous freezing nucleation of aqueous solution droplets (an important cirrus formation mechanism below -40°C) suggests that substantial ice-supersaturation (>40%) must be present in the tropopause region (Koop et al., 2000).”

In situ measurements have confirmed this:

Recent measurements made near the tropical tropopause during the NASA Cirrus Regional Study of Tropical Anvils and Cirrus Layers - Florida Area Cirrus Experiment (CRYSTAL-FACE) indicate persistent ice saturation ratios (s i ) of about 1.2–1.3 in cold ice clouds
source

and:

the researchers examined the relative humidity with respect to ice (RHI) in the three regions. They found that ice supersaturation (RHI > 100%) occured most frequently in the ice crystal formation region where cloud updraft velocities are typically the strongest, but also occurred frequently in the growth region.

Specifically, their study showed that ice supersaturation occurred about 31% of the time in cirrus clouds, confirming existing assumptions regarding the frequency of homogenous (non-aerosol related) cirrus formation. However, they also found that ice supersaturation often occurred at temperatures warmer than -40C, when heterogeneous (aerosol-related) cirrus formation typically occurs. This type of ice formation results in smaller ice particles, thereby increasing the resulting reflectivity of the cloud.
source

This has been documented for quite some time.

The existence of cloud free air masses in the state of supersaturation with respect to ice was proven almost 60 years ago. E. Glückauf (1945) found from hygrometer data obtained over southern England that (very high) supersaturation with respect to ice occurs very frequently in the upper troposphere. H.Weickmann concluded in his 1945 review paper on "Shapes and formation of atmospheric ice crystals" (Weickmann 1945) that ice crystals in the atmosphere, i.e. cirrus clouds, form mainly via the water phase and not as soon as ice saturation is reached. He characterized the ice forming regions in the upper troposphere and the (lowermost) stratosphere as regions of high ice-supersaturation but with small absolute humidity.

“Fine,” you say, “but what does this have to do with chemtrails?”
Well, nothing, since chemtrails don’t exist. But it does have a lot to do with contrails and more importantly, the formation of persistant contrails.

A good marker of ISSRs (ice-supersaturated regions) is persistent condensation trails (contrails) when the sky is otherwise free of clouds. Since the mixing process in an aircraft exhaust plume can create very high degrees of supersaturation even in dry ambient air, the formation of contrails does not require as high ambient humidity as the formation of natural cirrus. Contrails can therefore decorate the sky when no cirrus clouds are around. Contrail persistence however requires at least ice saturation.
(from the above link)

Therefore, once you understand the nature of ice supersaturation, the presence of persistent contrails in hardly a surprise.

Here, by the way, is the link to Thermit’s report:

www.chemtrailcentral.com...

As I mentioned to Thermit when I provided him a critique of the report (which critique he had requested), the study is an extremely ambitious one, and, as such, involves several measurements which are not relevant to the goals of the study.

I’d mentioned that a simpler approach would be to ask the following questions:

1. Can we correlate contrails with atmospheric conditions?

In order to do this, of course, we’d have to have the altitude for each aircraft which creates a contrail, which means it’d have to show up as identified with altitude, vector, etc on the FE screen. Now you might say that this would eliminate from the study any of then “unidentified” aircraft, most of which are purported to be military. I know; but we’ll get back to them in a minute.

The next step would be to build a table of observed aircraft contrails. The number of days which it is overcast is irrelevant, since we wouldn’t be taking any measurements that day anyway. The table header would look like this:

Aircraft********Contrail Duration********Altitude********Temperature********Humidity

The time of the aircraft flight, its vector, speed, etc. are irrelevant, because all you want to do is to correlate the persistent contrail to the temperature/humidity

You’d get the flight number and altitude from FE, contrail duration from your own timed observation, and Temperature/Humidity from GOES atmospheric soundings. Noter that Thermit splits the difference in many cases by interpolating temperatures from neighboring regions; this is not the greatest thing around, since the atmosphere is very dynamic even over a 5000-feet altitude delta, but it’s the best we can do, and no one would fault Thermit for his interpolation.

What would this show? Well, you’d probably use a binomial distribution (or maybe a Poisson distribution, if the incidence is very low) to predict whether a contrail would be found at a particular temperature/humidity regime. But the actual measurement itself would be a simple correlative of “contrail duration of x or greater seconds” and “temperature is below minus 40 deg and RH is 100%” If it’s statistically significant within, say, the first sigma, you’ve pretty much determined what’s causing the contrails that persist for (plug in your number) of seconds.

2. Can you correlate persistent contrails with unidentified aircraft?

This is a lot easier, because all you have to do is to see an aircraft which doesn’t show up on the FE log, and time the persistence of its contrails (if it has any). Let’s say that, in a given week, you see 171 identifiable aircraft of which 134 produce contrails of interest (“interest” being persisting for a predetermined number of seconds). During that same period, you see 16 unidentifiable aircraft of which 14 produce contrails of interest.

Simple math shows that the commercial aircraft have an n of 0.78 and the unidentified aircraft have an n of 0.875 which, given the small sample size is statistically insignificant. So you could conclude that there isn’t any difference between a military or a civilian aircraft; they’re both equally likely, using binomial distribution, to produce contrails of interest.

But what if the commercial aircraft have an n of 0.1 and the military aircraft have an n of 0.85, and you have a significant sample?

Well, you can make several observations:

1. the military aircraft are flying at a higher altitude.

2. the military aircraft are using different fuel additives, such as Prist, which results in a different combustion characteristic.

3. The military aircraft are flying using different flight rules for their engines than are the commercial aircraft.

4. The military aircraft are emitting something other than the typical combustion byproducts and water vapor.

Now which one of those reasons is the real one? Well, you can’t tell; there’s just not enough information available.

But, unfortunately, despite all the graphs, Thermit never provides the basic correlation. He shows a lot of data, but not all of it, and it’s simply not organized right. But the good thing is that at leat he’s doing some real research. What needs to be done is to design the study with a lot more rigor, and do it again – and again – and again.
