TL;DR: The WeCare project (Utilizing Weather information for Climate efficient and eco-efficient future aviation) as mentioned in this paper aimed at finding solutions for reducing the climate impact of aviation based on an improved understanding of the atmospheric impact from aviation by making use of measurements and modeling approaches.
Journal ArticleDOI
Numerical simulations of contrail-to-cirrus transition – Part 1: An extensive parametric study
TL;DR: The sensitivity of microphysical, optical and geometric contrail properties to relative humidity RHi, temperature T and vertical wind shear s was investigated in an extensive parametric study.
Journal ArticleDOI
Factors controlling contrail cirrus optical depth
TL;DR: In this article, an analytical microphysical cloud model is presented and validated that captures the processes of formation of contrail cirrus by depositional growth and sedimentation of ice particles and horizontal spreading due to wind shear.
Journal ArticleDOI
Numerical simulations of contrail-to-cirrus transition – Part 2: Impact of initial ice crystal number, radiation, stratification, secondary nucleation and layer depth
TL;DR: In this article, the authors investigated the effect of the relative humidity, temperature, and vertical wind shear on the evolution of the contrail-to-cirrus transition.
Journal ArticleDOI
Study of contrail microphysics in the vortex phase with a Lagrangian particle tracking model
Simon Unterstrasser,Ingo Sölch +1 more
TL;DR: In this article, an existing model for contrail vortex phase simulations with a 2-moment bulk micro-physics scheme was upgraded with a newly developed state-of-the-art microphysics module (LCM) which uses Lagrangian particle tracking.
