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

Feasibility test of per-flight contrail avoidance in commercial aviation [PDF]
Communications EngineeringContrails, 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 ...

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

Tracing contrails within cirrus clouds and their climate effect [PDF]
Nature CommunicationsAircraft contrails are not just streaks in clear blue skies - they represent a significant source of warming from the aviation sector. Two new studies reveal that their climate impact is more complex than previously thought, as many contrails may form ...

How Well Can Persistent Contrails Be Predicted?
Aerospace, 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 ...

Simulated radiative forcing from contrails and contrail cirrus [PDF]
Atmospheric Chemistry and Physics, 2013 A comprehensive general circulation model including ice supersaturation is used to estimate the climate impact of aviation induced contrails. The model uses a realistic aviation emissions inventory for 2006 to initiate contrails, and allows them to ...

Design of a Hydrogen Aircraft for Zero Persistent Contrails
Aerospace, 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.

Meteorological Conditions That Promote Persistent Contrails
Applied Sciences (Switzerland), 2022 Climate-impacting contrails need ice (super-)saturation to persist longer than a few minutes. However, this simple criterion cannot be easily applied for the prediction of persistent contrails.

Understanding the role of contrails and contrail cirrus in climate change: a global perspective [PDF]
Atmospheric Chemistry and PhysicsGlobally, emissions from aviation affect Earth's climate via complex processes. Contrail cirrus and carbon dioxide emissions are the largest factors contributing to aviation's radiative forcing on climate.
