Quantification of the radiative forcing of contrails embedded in cirrus clouds [PDF]

open access: yesNature Communications
Aviation leads to the emission of CO2 but also exerts non-CO2 effects on climate, such as line-shaped condensation trails (contrails) and contrail cirrus that are known to cause warming. However, little is known about the climate effect of contrails that

Influence of Sustainable Aviation Fuels on the Formation of Contrails and Their Properties

open access: yesEnergies, 2021
Condensation trails and contrail cirrus are currently responsible for the largest contribution to radiative forcing in the aviation sector, yet they have lifetimes of only a few hours.

How Well Can Persistent Contrails Be Predicted?

open access: yesAerospace, 2020
Persistent contrails and contrail cirrus are responsible for a large part of aviation induced radiative forcing. A considerable fraction of their warming effect could be eliminated by diverting only a quite small fraction of flight paths, namely those ...

Design of a Hydrogen Aircraft for Zero Persistent Contrails

open access: yesAerospace, 2023
Contrails are responsible for a significant proportion of aviation’s climate impact. This paper uses data from the European Centre for Medium-Range Weather Forecasts to identify the altitudes and latitudes where formed contrails will not persist.

On the Lifetimes of Persistent Contrails and Contrail Cirrus

open access: yesJournal of Geophysical Research: Atmospheres
Abstract Prediction of contrail cirrus persistence is highly problematic for models, in part due to a poor representation of intertwined microphysical and dynamical processes controlling contrail evolution in large‐scale ice‐supersaturated areas.

On the Life Cycle of Individual Contrails and Contrail Cirrus [PDF]

open access: yesMeteorological Monographs, 2017
Abstract The life cycle of individual (initially line shaped) contrails behind aircraft and of contrail cirrus (aged contrails mixed with other ice clouds) is described. The full contrail life cycle is covered, from ice formation for given water, heat, and particulate emissions; to changes in the jet, wake, and dispersion phases; through

The Application of a Convolutional Neural Network for the Detection of Contrails in Satellite Imagery

open access: yesRemote Sensing, 2023
This study presents a novel approach for the detection of contrails in satellite imagery using a convolutional neural network (CNN). Contrails are important to monitor because their contribution to climate change is uncertain and complex.

Visual Analysis and Detection of Contrails in Aircraft Engine Simulations. [PDF]

open access: yesIEEE Trans Vis Comput Graph, 2023
Contrails are condensation trails generated from emitted particles by aircraft engines, which perturb Earth's radiation budget. Simulation modeling is used to interpret the formation and development of contrails.

Most long-lived contrails form within cirrus clouds with uncertain climate impact. [PDF]

open access: yesNat Commun
Contrail-cirrus is considered the most important component of aviation-induced climate impact. However, a reliable assessment requires better understanding of their radiative effects.

Feasibility test of per-flight contrail avoidance in commercial aviation [PDF]

open access: yesCommunications Engineering
Contrails, formed by aircraft engines, are a major component of aviation’s impact on anthropogenic climate change. Contrail avoidance is a potential option to mitigate this warming effect, however, uncertainties surrounding operational constraints and ...
