- A £5 million trial is examining whether AI can assist in the reduction or removal of contrails from aircraft
- Contrails appear when the exhaust from aircraft engines hits the cold, high-altitude air, which creates ice crystals
- Also known as vapour trails, contrails are believed to contribute to climate change
Google, the Met Office, and the UK Government are cooperating with NATS (formerly National Air Traffic Services) and the University of Cambridge and Imperial College London on Operation Blue Skies, which aims to reduce or remove contrails from aircraft traveling from Europe to the USA and Canada.
