Contrails and Their Dependence on Meteorological Situations

open access: yesApplied Sciences
Contrails created by aircraft are a very hot topic today because they contribute to the warming of the atmosphere. Air traffic density is very high, and current forecasts predict a further significant increase.

Linear Contrails Detection, Tracking and Matching with Aircraft Using Geostationary Satellite and Air Traffic Data

open access: yesAerospace, 2023
Climate impact models of the non-CO2 emissions of aviation are still subject to significant uncertainties. Condensation trails, or contrails, are one of these non-CO2 effects. In order to validate the contrail simulation models, a dataset of observations

Tracing contrails within cirrus clouds and their climate effect [PDF]

open access: yesNature Communications
Aircraft 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 ...

Núvols d’avions: De la pseudociència dels ‘chemtrails’ a la ciència dels ‘contrails’ [PDF]

open access: yesMètode Science Studies Journal: Annual Review, 2018
Les afirmacions i els arguments més freqüents trobats en fòrums i pàgines web de pseudociència en favor de l’existència dels deixants dels avions, que anomenen chemtrails, es refuten a partir de l’explicació científica del procés de formació dels ...

Simulated radiative forcing from contrails and contrail cirrus [PDF]

open access: yesAtmospheric 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 ...

Powering aircraft with 100 % sustainable aviation fuel reduces ice crystals in contrails [PDF]

open access: yesAtmospheric Chemistry and Physics
Powering aircraft by sustainable aviation fuels (SAFs) is a pathway to reduce the climate impact of aviation by lowering aviation lifecycle CO2 emissions and by reducing ice crystal numbers and radiative forcing from contrails.

Contrails and their impact on shortwave radiation and photovoltaic power production – a regional model study [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
A high-resolution regional-scale numerical model was extended by a parameterization that allows for both the generation and the life cycle of contrails and contrail cirrus to be calculated. The life cycle of contrails and contrail cirrus is described

Dehydration effects from contrails in a coupled contrail–climate model [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
The uptake of water by contrails in ice-supersaturated air and the release of water after ice particle advection and sedimentation dehydrates the atmosphere at flight levels and redistributes humidity mainly to lower levels.

Understanding the role of contrails and contrail cirrus in climate change: a global perspective [PDF]

open access: yesAtmospheric Chemistry and Physics
Globally, 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.
