Regional and Seasonal Dependence of the Potential Contrail Cover and the Potential Contrail Cirrus Cover over Europe [PDF]
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

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.

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 ...

Impacts of multi-layer overlap on contrail radiative forcing [PDF]
Atmospheric Chemistry and Physics, 2021 Condensation trails (“contrails”) which form behind aircraft are estimated to cause on the order of 50 % of the total climate forcing of aviation, matching the total impact of all accumulated aviation-attributable CO2.

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.

The climate opportunities and risks of contrail avoidance [PDF]
Nature CommunicationsNavigational contrail avoidance presents an opportunity for rapid reduction in aviation-attributable warming. Here, we use the Aviation Climate and Air Quality Impacts model to evaluate the global temperature changes associated with contrail avoidance ...

Air traffic and contrail changes over Europe during COVID-19: a model study [PDF]
Atmospheric Chemistry and Physics, 2021 The strong reduction of air traffic during the COVID-19 pandemic provides a unique test case for the relationship between air traffic density, contrails, and their radiative forcing of climate change.

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.

Bulletin of the American Meteorological Society, 2010 This article reviews the current state of understanding of the science of contrails: 1) how they are formed, 2) their microphysical properties as they evolve into contrail cirrus and whether their microphysical properties can be distinguished from natural cirrus, and 3) the ice-nucleating properties of soot aerosols and whether these aerosols can ...
