White trails are frequently observed in the wake of aircraft. In some cases, these can turn into cirrus clouds which, depending on their persistence in the atmosphere, can alter the planet’s radiation balance and possibly contribute to global warming.

While certain local humidity and temperature conditions are required for the formation of these trails, the propulsion system and fuel directly impact their characteristics and their ability to evolve into cirrus clouds.

Afternoon of conferences with:

  • Engine emissions: a review of new fuels
    by Michel DESAULTY, former Chief Engineer at SAFRAN Aircraft Engines, member of the AAE
  • Aircraft contrails : what impact on the climate?
    by Daniel CARIOLLE, former director of research at Météo-France, member of the AAE

This conference will take place face-to-face at the Cité des sciences et de l’industrie, Paris.

Free admission in the limit of available seats.

Broadcast live on the Youtube channel of the Cité des sciences et de l’industrie
