A contrail (a term introduced for “condensation trail” in 1942 by British pilots) is a visible cloud forming behind aircraft, mainly due to water vapor emissions from the engines. Contrails were first observed behind propeller-driven aircraft in 1915 but form as well from the exhaust of jet engines in cold ambient air (Schumann 1996a).

Abstract Several lines of evidence indicate that aviation‐induced cirrus clouds contribute to global warming. These clouds produce both longwave and shortwave radiative forcing, yet their climate impacts are not well understood. To improve understanding of the climate effects of radiative forcing associated with aviation‐induced cirrus clouds, we use ...

Assessing the climate impact of the AHEAD multi-fuel blended wing body
Air traffic is important to our society and guarantees mobility especially for long distances. Air traffic is also contributing to climate warming via emissions of CO2 and various non-CO2 effects, such as contrail-cirrus or increase in ozone ...

Feasibility of climate-optimized air traffic routing for trans-Atlantic flights [PDF]
Current air traffic routing is motivated by minimizing economic costs, such as fuel use. In addition to the climate impact of CO2 emissions from this fuel use, aviation contributes to climate change through non-CO2 impacts, such as changes in ...

Abstract A new cirrus cloud parameterization for the ICOLMDZ atmospheric general circulation model (AGCM) is presented. Prognostic equations for cloud fraction, ice water content and cloudy water vapor are introduced, and the processes that affect these quantities are parameterized.

Benchmarking and improving algorithms for attributing satellite-observed contrails to flights [PDF]
Condensation trail (contrail) cirrus clouds cause a substantial fraction of aviation's climate impact. One proposed method for the mitigation of this impact involves modifying flight paths to avoid particular regions of the atmosphere that are conducive ...

Evaluation of the use of radiosonde humidity data to predict the occurrence of persistent contrails [PDF]
Regular visual observations of persistent contrails over Reading, UK, have been used to evaluate radiosonde measurements of temperature and humidity defining cold ice-supersaturated atmospheric regions which are assumed to be a necessary condition for ...

A methodology for in-situ and remote sensing of microphysical and radiative properties of contrails as they evolve into cirrus [PDF]
Contrails and especially their evolution into cirrus-like clouds are thought to have very important effects on local and global radiation budgets, though are generally not well represented in global climate models.
