EUROCONTROL: State-of-the-art contrails observations

Contrails observations to reduce climate impact Contrails are the cloud-like formations created when aircraft exhaust mixes with cold high-altitude air. Recent studies suggest that their climate impact may be greater than that of carbon dioxide emissions from aviation, which has propelled contrails to the forefront of climate research, as the aviation industry seeks to achieve climate neutrality by 2050. Understanding the formation, persistence, and
