Contrails Map

It states that half of aircraft pollution is from contrails made of aircraft soot.

I’d like to see the literature and discovery of aircraft soot.

As an engineer who has built aircraft, I find this fascinating. I would like to measure my amount of soot. How does one go about measuring how much soot I have?

Obviously if my exhaust ports are black that’s bad but I’m genuinely curious about this as I’ve always assumed “black smoke bad, white smoke ok”. As for contrails, disturbing the atmosphere is going to cause some freezing (clouds) at that altitude, at that temperature. How do you suggest we mitigate that? Fly lower and burn more fuel? Fly less and tell people to take the train or that their package will arrive next week?

I was expecting this to be a gag about chemtrails. I am glad I was wrong.

Amazing visualisation, an excellent tool.

Are there other sites that can suggest how much of an issue it is, and how much flight plan tweaking could improve this.

Remember kids a 1° C rise in temperature can mean 7% more water vapour in the air, and with water vapour being a greenhouse gas itself this can cause heating and holding yet more water.

The team behind this is world-class. Among other things, they have developed a python library that could be used to model contrails in your own projects.

I'm not following the logic why contrails cause net warming.

Why nuclear blasts - that also introduce lots of particles in atmosphere cause a cooling effect - "nuclear winter"?

Would be great for shiptracks, too— which used to mitigate 1/3 of the warming impact of maritime shipping — until the 2022 clean fuel standards were implemented.
