Simulations of Contrail Optical Properties and Radiative Forcing for Various Crystal Shapes [PDF]
, 2011 The aim of this study is to investigate the sensitivity of radiative-forcing computations to various contrail crystal shape models. Contrail optical properties in the shortwave and longwave ranges are derived using a ray-tracing geometric method and ...

Global Modeling of the Contrail and Contrail Cirrus Climate Impact [PDF]
Bulletin of the American Meteorological Society, 2010 Despite considerable technological advances, aviation impacts on global climate are significant and may constitute a future constraint on the continued growth of air travel. The most important but least understood component in aviation climate impact assessments are contrails, which form as line-shaped ice clouds (linear contrails) and transform into ...

A “greenhouse gas balance” for aviation in line with the Paris Agreement
WIREs Climate Change, Volume 14, Issue 5, September/October 2023., 2023 CO2‐equivalent emissions from aviation in 2050 calculated with different emissions metrics and the corresponding amounts of CO2 removal for achieving net zero greenhouse gas emissions (“balance”). Abstract The effects of aviation on climate pose unique policy challenges.

Aircraft clouds: from chemtrail pseudoscience to the science of contrails [PDF]
, 2017 The most frequent statements and arguments found in pseudoscience websites and forums supporting the existence of so-called aircraft chemtrails can be refuted with a scientific explanation of the processes resulting in the formation of condensation or ...

Potential Impacts on Ozone and Climate From a Proposed Fleet of Supersonic Aircraft
Earth's Future, Volume 11, Issue 4, April 2023., 2023 Abstract There has been renewed interest in developing commercial supersonic transport aircraft due to the increased overall demands by the public for air travel, the aspiration for more intercontinental travel, and the desire for shorter flight times.

The Role of Mineral Dust Aerosol Particles in Aviation Soot‐Cirrus Interactions
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 3, 16 February 2023., 2023 Abstract Predicting cirrus cloud properties with confidence requires a sound understanding of the relative roles of homogeneous and heterogeneous ice formation. This study explores the effect of mineral dust and contrail‐processed aviation soot particles as ice‐nucleating particles (INPs) competing with liquid solution droplets in cirrus formation.

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

A review of air travel behavior and climate change
WIREs Climate Change, Volume 14, Issue 1, January/February 2023., 2023 Air travel mitigation responses. Abstract Air transport challenges the world's net‐zero carbon ambitions. The sector has consistently grown and causes warming as a result of both CO2 and other, short‐lived emissions. Two principal solutions have been proposed to reduce the contribution of aviation to climate change: innovations of technology and the ...

Properties of young contrails – a parametrisation based on large-eddy simulations [PDF]
Atmospheric Chemistry and Physics, 2016 Contrail–cirrus is probably the largest climate forcing from aviation. The evolution of contrail–cirrus and its radiative impact depends not only on a multitude of atmospheric parameters, but also on the geometric and microphysical ...
