Short summary
This work presents the link between the chemical composition and the optical properties of the aerosol emissions of an aircraft turbofan using conventional and alternative fuels. A high organic carbon fraction at low thrusts is linked to high single scattering albedos. The optical properties at cruise conditions are used to evaluate the radiative forcing efficiency of aircraft aerosol emissions, which have a substantial warming effect when emitted over highly reflective surfaces such as snow.
