Contrails, the cloud-like streaks left in the sky by jets, are artificial clouds that are similar in nature to natural cirrus clouds, the thin, high-altitude clouds that spread across the sky in wispy fingers. Contrails, like cirrus clouds and unlike thicker, lower-altitude clouds, can allow a considerable amount of solar radiation to penetrate to the Earth's surface, warming the planet. Contrails can also trap that energy in the Earth's atmosphere, increasing the warming effect. As aviation looks to grow in the coming years, there is concern about the increasing impact of contrails on climate change. A new interdisciplinary project will use expertise in aerodynamics, satellite imaging, and sustainability to identify opportunities to mitigate the climate impacts of contrails.
