Formation and radiative forcing of contrail cirrus. [PDF]
Nat Commun, 2018 Aircraft-produced contrail cirrus clouds contribute to anthropogenic climate change. Observational data sets and modelling approaches have become available that clarify formation pathways close to the source aircraft and lead to estimates of the global ...

Towards Determining the Contrail Cirrus Efficacy [PDF]
Aerospace, 2021 Contrail cirrus has been emphasized as the largest individual component of aircraft climate impact, yet respective assessments have been based mainly on conventional radiative forcing calculations.

Contrail formation within cirrus: ICON-LEM simulations of the impact of cirrus cloud properties on contrail formation [PDF]
Atmospheric Chemistry and Physics, 2022 Contrail formation within natural cirrus introduces large perturbations in cirrus ice crystal number concentrations, leading to modifications in cirrus microphysical and optical properties.

The social costs of aviation CO2 and contrail cirrus [PDF]
Nature CommunicationsThe radiative forcing (RF) of contrail cirrus is substantial, though short-lived, uncertain, and heterogeneous, whereas the RF from CO₂ emissions is long-term and more predictable.

Contrail cirrus radiative forcing for future air traffic [PDF]
Atmospheric Chemistry and Physics, 2019 The climate impact of air traffic is to a large degree caused by changes in cirrus cloudiness resulting from the formation of contrails. Contrail cirrus radiative forcing is expected to increase significantly over time due to the large projected ...

Aviation Contrail Cirrus and Radiative Forcing Over Europe During 6 Months of COVID‐19 [PDF]
Geophysical Research Letters, 2021 The COVID‐19 pandemic led to a 72% reduction of air traffic over Europe in March–August 2020 compared to 2019. Modeled contrail cover declined similarly, and computed mean instantaneous radiative contrail forcing dropped regionally by up to 0.7 W m−2 ...

Aerospace, 2022 Ambient weather conditions strongly impact contrail formation and persistence. The implementation of contrail avoidance and mitigation strategies, therefore, requires regional and altitude-dependent information on the frequency of contrail occurrence. To

Regional and seasonal impact of hydrogen propulsion systems on potential contrail cirrus cover
Atmospheric Environment: XThe decarbonization of air transportation requires novel propulsion concepts in order to replace fossil kerosene powered gas turbines. Within various options, H2 based propulsion is one of the most promising candidates, at least for regional and short ...

Observations of microphysical properties and radiative effects of a contrail cirrus outbreak over the North Atlantic [PDF]
Atmospheric Chemistry and Physics, 2023 Contrail cirrus constitute the largest radiative forcing (RF) component to the total aviation effect on climate. However, the microphysical properties and radiative effects of contrail cirrus and natural cirrus clouds in the same meteorological ...

Upper-tropospheric slightly ice-subsaturated regions: frequency of occurrence and statistical evidence for the appearance of contrail cirrus [PDF]
Atmospheric Chemistry and Physics, 2023 Microphysical, optical, and environmental properties of contrail cirrus and natural cirrus were investigated by applying a new, statistically based contrail–cirrus separation method to 14.7 h of cirrus cloud measurements (sampling frequency 1 Hz, max ...
