Discussion in 'Contrails and Chemtrails' started by Mick West, Oct 1, 2012.
Here's a close-up of NZ
Wellington also occasionally gets overflights from Aus to Sth America, and Dunedin & Invercargil get overflights of A320's & C0-17's from Christchurch to Antarctica that have caused at least 1 chemtrail letter to the editor of the ODT resulting in this piece in reply!
At least some of ANZ's 737's have ADSB - right now I can see NGR on ANZ421 (Akl-Wlg) about 20-30 miles NNW of New Plymouth at 35,575 ft
Reminds me of this post regarding NZ flight altitudes over at Nutbars. Good times, good times...
Can you provide one of the Bay Area (Northern California)?
Also, many CT's think that they are spraying all over the Pacific. Do you see flight paths that can corroborate with those claims?
Here's the Bay Area,
and the North East Pacific, which shows a similar set of routes to the North Atlantic.
What the chemtrail promoters often point to are ship trails, very different to contrails, see:
This is interesting. I've colored the westward flights blue, and the eastward flights green. There's a very distinct separation for ocean routes for the trade winds/jet stream.
There's still a separation over land, but less pronounced. Probably more to do with collision avoidance, ATC.
This is the Socal region, with color coded east/west. Segments below 30,000 are in gray.
You can see the various streams of arriving and departing traffic, particularly from LAX and San Diego
Handy hint, all of these images are likely a bit larger than they seem in your browser, so you can download them (right click, save as..), and zoom in.
I recently started using these images on ATS (where I post as "Uncinus"), maybe it will help people visualize what's going on overhead.
I've fixed a few bugs and made some improvements - specifically interpolating great circle routes for patchy data (from ADS-B). This adds quite a bit to the world map:
There seem to be some bugs remaining in the data or their interpolation - quite a few routes end at the double zero point in Gulf of Guinea.
Is there a map of actual trans-african routes? In particular, I am interested in those that may overfly the Eye of the Sahara in Mauritania, but could not find where to look.
Yeah, I suspect that's a problem with the data. Could be flights to Arfrica with no end data, but I can't imaing there's a ADS-B station that would be picking up data at 0,0. I think I'll just filter out point near 0,0 (-1,-1 to 1,1) as spurious.
Not that I'm aware of. At some point I'd like to add the capability to take a file of airport code pairs (LHR,LAX) and plot great circles, that way you could generate a (somewhat idealized) route map for various places.
Flights to Dakar or Banjul from Europe seem like they would likely go near there. There's also Cap Skirring in Southern Senegal - some tourist traffic, and certainly flights from Paris.
Here's a different take on things. I scanned the data to extract all the origin->dest endpoints, and then joined them all with their great circle routes. While it does not show the exact track the planes fly it's a cleaner representation, and all the tracks are complete. The ADS-B data suffers when one endpoint is not recorded, then you get a short truncated path at the other end. I might fix that in the future by combining this for the missing segments.
US routes Detail:
Arrivals (Red) and Departures (Green) from London area airports. Note the holding stacks for LHR.
Scandinavia. There must be several places in the north of the region (Norway, Sweden, Finland) that only get very occasional contrails. I wonder how many chemtrailers they get there. (Not that there are that many people there).
Someone notices them - Google search
Some more advanced filtering:
Lots of flights get funneled through the Las Vegas area because of the military exclusion zones in the airspace around it. They have more high altitude overflights than Los Angeles.
It would be interesting to see pics from chemtrail activists in hawaii.
Is that when they are dropping down for landing?
That, but also regional flights and smaller planes, to get the landing zones see the <10K chart:
What an interesting thread. My main base is Baja California, Mexico, near San Jose del Cabo. I'd always assumed there weren't contrails because of the level of humidity and lack of traffic - but perhaps there aren't any flights above 30,000 feet either?
I do actually know some people who live here "because there aren't any chemtrails".
I'm back in southern Baja now and staggered by the volume of traffic compared to previous years. I remember first being here 19 years ago and being annoyed because one day one plane flew over the mountains I was camping in - now there are spells when it's almost constant. Interesting that if the planes here did leave contrails and I was so inclined, probably what I'd be remembering was chemtrail-free skies in the old days, and tons of spraying now.
Anyways, any chance Mick can do one of those nice graphics showing all flights over 24-hours in my neighbourhood so I can: a) get a handle on what's going on overhead; and b) move somewhere with less noise please?
