A Stylized Study of the Climate Response to Longwave and Shortwave Forcing at the Altitude of Aviation‐Induced Cirrus

Earth's Future, Volume 13, Issue 10, October 2025.
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 ...

Benchmarking and improving algorithms for attributing satellite-observed contrails to flights [PDF]

Atmospheric Measurement Techniques
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 ...

A New Prognostic Parameterization of Subgrid Ice Supersaturation and Cirrus Clouds in the ICOLMDZ AGCM

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 8, August 2025.
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.

A methodology for in-situ and remote sensing of microphysical and radiative properties of contrails as they evolve into cirrus [PDF]

Atmospheric Chemistry and Physics, 2012
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.

The role of air transportation in emissions through energy usage: Evidence from global data

Natural Resources Forum, Volume 49, Issue 3, Page 2594-2618, August 2025.
Abstract Investigating the role that air transportation plays in regard to carbon emissions offers several valuable insights and contributions that are critical for addressing climate change and promoting sustainable development as far as climate mitigation, policy development and evaluation, technological innovation, public awareness engagement ...

Simulation of a contrail formation and early life cycle for a realistic airliner geometry [PDF]

Atmospheric Chemistry and Physics
Contrails – ice clouds forming in aircraft wakes – may have a radiative impact up to twice that of CO2 emissions from aviation, though significant uncertainties remain.

Contrail life cycle and properties from 1 year of MSG/SEVIRI rapid-scan images [PDF]

Atmospheric Chemistry and Physics, 2015
The automatic contrail tracking algorithm (ACTA) – developed to automatically follow contrails as they age, drift and spread – enables the study of a large number of contrails and the evolution of contrail properties with time. In this paper we present a

Simulated contrail-processed aviation soot aerosols are poor ice-nucleating particles at cirrus temperatures

Atmospheric Chemistry and Physics
. Aviation soot surrogates processed in contrails are believed to become potent ice nuclei at cirrus temperatures. This is not verified for real aviation soot, which can have vastly different physico-chemical properties.

Transient Darkening of Low‐Level Liquid Clouds by the 2022 Hunga Lamb Wave Observed in GOES‐R Imagery

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The 15 January 2022 eruption of the Hunga volcano generated a Lamb wave, a global atmospheric pressure perturbation which propagates purely horizontally at the speed of sound. Far‐field observations of the daytime passage of the Lamb wave by the Geostationary Operational Environmental Satellite‐R (GOES‐R) series, revealed unexpected ...

On the Potential Role of Lubrication Oil Particles in Contrail Formation for Kerosene and Hydrogen Combustion

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The radiative forcing caused by contrail cirrus is nonlinearly influenced by the number of ice crystals formed in the exhaust plume behind an aircraft engine. This ice crystal number strongly depends on the properties (number, size, and solubility) of condensation nuclei in the plume available for droplet activation with subsequent freezing ...
