Contrails, short for condensation trails, are the white streaks often seen in the sky behind aircraft. The International ...

Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails ...

From the top of a plane wing, another airplane is seen flying above clouds in a blue sky, leaving a contrail in its wake. In spring 2023, scientists aboard a research aircraft chased an Airbus A321neo ...

The contrail clouds formed by jet engines contribute to global warming. In-flight measurements of the particles emitted and contrails produced by a passenger jet show that contrails are formed through ...
