"The Advanced Research and Innovation Agency (ARIA) - a government backed body - is funding nearly £60m that could allow real-world experiments, including in the UK.

Paper on how "Low-Altitude High-Latitude Stratospheric Aerosol Injection Is Feasible With Existing Aircraft" https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024EF00...

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?

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.

I would however recommend testing it on a slower internet connection and a lower end device. Because I was spending 90% of my time in the "loading data" phases, and once the intro was done, the thing ran at one frame per second and I was not able to use it. (I have 5G and I bought my phone last year.)

We are seeking a high level full stack engineer to join the team to work on infrastructure for this and other efforts. Please reach out if interested - info@contrails.org

Examples:

    1. System and Method for Irradiation of Planet Surface Areas
    2. Method and Apparatus for Altering a Region in the Earth’s Atmosphere, Ionosphere, and/or Magnetosphere
    3. Broadcast Dissemination of Trace Quantities of Biologically Active Chemicals
    4. Method and Apparatus for Creating an Artificial Electron Cyclotron Heating Region of Plasma
    5. Method and Apparatus for Triggering a Substantial Change in Earth Characteristics and Measuring Earth Changes
    6. Planetary Weather Modification System

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

Including aspects like water pollution and health risks would add significant value to this already impressive initiative.

Thank you for sharing!

If the future of aviation is similar flight densities everywhere then people might actually begin to care about this topic.
