Contrails and their impact on shortwave radiation and photovoltaic power production – a regional model study [PDF]
A high-resolution regional-scale numerical model was extended by a parameterization that allows for both the generation and the life cycle of contrails and contrail cirrus to be calculated. The life cycle of contrails and contrail cirrus is described

The Role of Mineral Dust Aerosol Particles in Aviation Soot‐Cirrus Interactions
Abstract Predicting cirrus cloud properties with confidence requires a sound understanding of the relative roles of homogeneous and heterogeneous ice formation. This study explores the effect of mineral dust and contrail‐processed aviation soot particles as ice‐nucleating particles (INPs) competing with liquid solution droplets in cirrus formation.

On the Transition of Contrails into Cirrus Clouds
In situ observations of the microphysical properties of upper-tropospheric contrails and cirrus clouds have been performed during more than 15 airborne missions over central Europe. Experimental and technical aspects concerning in situ characterization of ice clouds with the help of optical and nonoptical detection methods (preferably FSSP-300 and ...

Properties of young contrails – a parametrisation based on large-eddy simulations [PDF]
Contrail–cirrus is probably the largest climate forcing from aviation. The evolution of contrail–cirrus and its radiative impact depends not only on a multitude of atmospheric parameters, but also on the geometric and microphysical ...

Long-lived contrails and convective cirrus above the tropical tropopause [PDF]
This study has two objectives: (1) it characterizes contrails at very low temperatures and (2) it discusses convective cirrus in which the contrails occurred.

A contrail (a term introduced for “condensation trail” in 1942 by British pilots) is a visible cloud forming behind aircraft, mainly due to water vapor emissions from the engines. Contrails were first observed behind propeller-driven aircraft in 1915 but form as well from the exhaust of jet engines in cold ambient air (Schumann 1996a).

Systematic review of the impact of emissions from aviation on current and future climate [PDF]
Aviation emissions have an impact on the global climate, and this is consequently an active area of research worldwide. By adapting replicable and transparent systematic review methods from the field of evidence-based medicine, we aim to synthesise ...

Simulating contrail formation within cirrus in the high-resolution ICON-LEM model [PDF]
Contrail ice formation in ice supersaturated region and their impact on climate is often studied. However, contrail ice formation within cirrus and their impact on cirrus cloud properties are overlooked therefore, their climate impact is unknown ...

Sensitivity of radiative properties of persistent contrails to the ice water path [PDF]
The dependence of the radiative properties of persistent linear contrails on the variability of their ice water path is assessed in a two-stream radiative transfer model.
