Formation and radiative forcing of contrail cirrus. [PDF]
Nat Commun, 2018 AbstractAircraft-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 distribution of their microphysical and optical properties. While contrail cirrus enhance the

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.

Factors controlling contrail cirrus optical depth [PDF]
Atmospheric Chemistry and Physics, 2009 Aircraft contrails develop into contrail cirrus by depositional growth and sedimentation of ice particles and horizontal spreading due to wind shear.

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.

Statistical analysis of contrail to cirrus evolution during the Contrail and Cirrus Experiment (CONCERT) [PDF]
Atmospheric Chemistry and Physics, 2018 Air traffic affects cloudiness, and thus climate, by emitting exhaust gases and particles. The study of the evolution of contrail properties is very challenging due to the complex interplay of vortex dynamics and the atmospheric environment (e.g ...

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 ...

A contrail cirrus prediction model [PDF]
Geoscientific Model Development, 2012 A new model to simulate and predict the properties of a large ensemble of contrails as a function of given air traffic and meteorology is described.

Most long-lived contrails form within cirrus clouds with uncertain climate impact [PDF]
Nature CommunicationsContrail-cirrus is considered the most important component of aviation-induced climate impact. However, a reliable assessment requires better understanding of their radiative effects.

Emission metrics for quantifying regional climate impacts of aviation [PDF]
Earth System Dynamics, 2017 This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrail-cirrus formation and calculate the global and ...
