Contrails Observer

Aircraft contrails often grow into cirrus clouds that trap heat in the lower atmosphere and significantly add to global warming. Recent estimates show that contrail-cirrus warming is roughly equivalent to the warming caused by the greenhouse gas emissions of those same aircraft, or roughly 1 - 2% of all anthropogenic climate change.

The Contrails Observer app enables researchers and citizen scientists to observe contrail forming regions of the atmosphere from the ground. These observations will support the detection of contrail forming regions and improve weather forecasts to reduce contrail-climate impact of aviation.
