Description: This project aims at a better understanding of the formation of particles (contrail and aerosols in the wake of subsonic airplanes, in order to investigate the microphysical and radiative properties of contrails as function of the meteorological conditions during their life cycle, i.e. from the early phase of jet expansion to a cirrus like stage. Expected achievements are: 1) The determination of the range of variability of the microphysical and optical properties of contrails during their life cycle as function of the ambient meteorological conditions, 2) The determination of the basic physical processes that control the evolution and life cycle of contrails i.e. the derivation of relationships between the occurrence of persistent contrails and the meteorological properties of upper air masses (transition from young contrail to natural cirrus), 3) The determination of the basic physical processes that control the formation and evolution of the aerosols generated in the wake of an aircraft, 4) The investigation of the interactions between aerosol, contrails and subsequent cloud formation, 5) The parameterization schemes that describe the formation and dissipation of contrails as well as their radiative properties in order to use them in large scale circulationmodels (GCM's).
