Ok basically what Im proposing is that we research the atmospheroc conditions that occur when contrails (or chemtrails for those that dont believe in persistent contrails) are present.

The aim is to use weather balloon soundings, forecasts and weather observations, to substantiate wether the atmosphere is likely to produce contrails,and if they are likely to persist. Air traffic should also be monitored where possible, to determine the existence of planes that are in holding patterns, or how much air traffic is in a given area at a given time.

Photographic evidence of contrails is not compulsory, but would be appreciated. Especially where contrails are persisting. Its will also be useful to take into account any other cloud that is present, ie cirrus, to determine where the atmosphere is already moist. Any weather phenomenen such as halos, iridescence (coloured clouds) should also be noted.

To keep this an unbiased as possible, people from both the contrail and chemtrail side are welcome. We could possibly settle the argument once and for all (well at least for those sitting on the fence).

Note- Ive had this idea for a long time and now, given the last couple of contrail/ chemtrail threads, its probably a good time to bring it up.

Also want to add, that if this thread is succesful, then it may be, possibly made into a sticky. Im aiming for a years worth of data and information, as it would be advantageous to get information from all seasons, given that weather varies over different months.

Great Idea! I will participate , of course.

I do not have access to a digi cam right now, but will after Wednesday, so today yall have to rely on my word.

Looking outside, the weather is a pleasant (very) 73 with (according to Weather.com) 51% humidity. The sky is mostly cloudy, some clouds darker than other, with a few Simpson blue patches of sky peeking through. Not a chemtrail to be seen today.

I hope others can contribute to this thread, and we can discover some patterns that everyone on both sides can understand.

Thanks for your participation tater


What state were you in again? I would like to check the weather details and forcasts for the area

There is a post by a member from Seattle, Washington, regarding an observation made YESTERDAY, alleging the sighting of two airplanes making "chemtrails", turning around and passing repeatedly overhead.

This occured, as I said, 22 August between 1430 and 1730 PDT (let's see, that's 2130-0030 UTC)

It is from this post in a thread titled "Chemtrailes (sic) don't exist".

Unfortunately, the OP's original point, and meaning has been hijacked by hte "chemtrail" conspiracists.

All Im getting is a bucket load of low level moisture indicating the presence of a layer of low cloud in the area, meaning observing contrails would be unlikely

Edit to add- fifth column relative humidity


Clouds quite thick according to the weather balloon data



Here's the IR sat image too. As you can see, there is a large mass of low cloud present to the east of Seattle. In fact the entire area is shrouded in cloud. Im still trying to understand how contrails/ chemtrails were observed

Starred and flagged.

I know I have commented a ton on the subject, but I have zero attachment if an reasonable explanation was granted to what I have seen over the last few years.

I think this is a fantastic idea, as in a recent post, weedwhacker looked up the flight information in my city and conditions...as there were a ton of contrail/chemtrails yesterday, and none currently.

Good job Oz.

I am in the southwest of England, today we got bombarded with trails. They where laying them from early in the morning right through until about 16:00 this afternoon.
It was a really sunny day no "real clouds" in the sky. Tonight the sky is full of heavy clouds, I always wonder if they come out and lay the trails purposely before it rains? Are they cloud seeding?

Oz,

Out my window, there is not a ton of cloud cover at all. A few large puffy clouds but a ton of blue sky.

Yesterday, other then the large cloudy haze caused by the contrails, there were almost no clouds.

Im about to go check the weather deatils for England soon.

I dont know if you've heard me say before, but contrail persistence is a good indication of possible weather, as it suggests the upper troposphere is becoming moist. When frontal systems are approcahing, cirrus and cirrostratus is often the first cloud type seen. (contrails are regarded in the meteorological world as cirrus clous btw)

Its also not cloud seeding, as cloud seeding is performed at lower altitudes where rain bearing clouds are already present. Planes fly above theses clouds, in an area where cirrus is present. Cirrus clouds are composed completely of ice, and do not produce weather. Clouds they target for cloud seeding are cumulus, altostratus and altocumulus, and they release dry ice or silver iodide to encourage the growth of water droplets and supercooled water droplets to produce rain. Hope that explains it

Brocket- Thanks for the kind words. Next time would it be possible to take a photo as well? Id like to compare other clouds in the sky too

Also, you are probably right, the sat picture I produced is probably to recent to compare to your observations.

I will do my best to carry a camera the next week.

TYPICALLY the contrail activity happens on Thursdays and Saturdays, but I won't just pay attention these days.

Ok, excellent

Make sure you get photos on those days too though, so we can compare them to the other days of the week

Just as a matter of interest I would like to add this video to. Its a fantastic example of why the airforce is concerned with contrails. Its also a rare glimpse of contrails being formed close to another aircraft, in flight

You asked me to post my question in this thread about cloud seeding and whether it is common knowledge the Government changes the weather. However, I think you answered it with this.

Cirrus clouds are composed completely of ice, and do not produce weather.

Hope that explains it


So they can only do this with rain bearing clouds. Which would explain why we still have droughts. Which answers my other question.


Just in case you wanted to elaborate.

1. Is it common knowledge the Government changes the weather?

2. If so, why do some places still have droughts ?

We've been having pretty interesting weather in central PA for the last couple weeks. Absurd amount of ground-level humidity, but today its really nice. The sky is clear, but we've been getting some really heavy fog at night, so the ceiling disappears.

Haven't seen a contrail in a while, and they don't often stick around here, but the next time I see a good one I'll post it here.

I'll be going to New York next week too so I'll snap some photos there too.

Nice one VV, Im gonna get the weather balloon info for Michigan and post it.

You got nice deck of altocumulus there it appears. Your sat picture (the visible image) shows it quite good

Wow, thats a moist environment

I should mention what the columns mean as this data will be referred tro often

First column- Air pressure in hPa
Second column- Height in metres
Third column- Temperature in Celsius
Fourth column- Dewpoint in Celsius
Fifth column- Humidity in percent
Sixth column- Mixing rate (not that important)
Seventh column- Wind direction in degrees
Eigth column- Wind speed in knots

Next three columns are not important


Forgot to add that the humidity sensor seemed to have died late in the flight so its not possible to check out wether contrails arwe possible or not


Just our luck

Ok. Thanks for the explanation.

We get lots of those 'jet-trails' here, though there haven't been too many the last few weeks, except for a day or two.

Next time I see some I'll post the shots here.

Yep, it sure is. The Beijing olympics are one good example of how the tried to prevent precipitation. I know they have tried cloud seeding in great Britain and they also tried it in Queensland, here in Australia.



2. If so, why do some places still have droughts ?


Because cloud seeding is not guaranteed to work. Remember we need clouds first off, to be able to add the triggers to.

Its funny, becuase contrails are a good example of how cloud seeding should work, as the dust and water vapour from the exhaust encourages ice growth.
