Short summary
A large comprehensive data set of 3-D large eddy simulation (LES) of young contrails has been analysed. Parametrisations of the most important properties of young contrails, namely the ice crystal number and geometric depth, are provided taking into account the effect of many environmental and aircraft parameters. The parametrisation is suited to be incorporated in larger-scale models like GCMs.
