Aircraft engines are known to produce a large amount of particulate matter including combustion aerosols, sulphate droplets or ice particles formed in the expanding wake of the aircraft. The emitted particles can influence the chemical composition of the atmosphere by enhancing the background aerosol surface area density and the subsequent heterogeneous reactions that occur on the particles. Contrail formation and possible cloud coverage increase also modify the earth radiative budget and may contribute to the climate change.

已知飞机发动机产生大量颗粒物质，包括在飞机的膨胀尾流中形成的燃烧气溶胶、硫酸盐液滴或冰粒。排放的颗粒可以通过增加背景气溶胶表面积密度和随后在颗粒上发生的非均相反应来影响大气的化学组成。凝结尾迹的形成和可能的云覆盖的增加也改变了地球的辐射收支，并可能导致气候变化。
