Impact of host climate model on contrail cirrus effective radiative forcing estimates [PDF]
Atmospheric Chemistry and PhysicsEstimates of aviation effective radiative forcing (ERF) indicate that contrail cirrus is currently its largest contributor, although with a substantial associated uncertainty of ∼ 70 %.

Modelling contrail cirrus using a double-moment cloud microphysics scheme in the UK Met Office Unified Model [PDF]
Atmospheric Chemistry and PhysicsContrail cirrus is the largest contributor to aviation effective radiative forcing (ERF), but remains highly uncertain (∼ 70 %). Recent research has highlighted the critical role of cloud microphysical schemes in contrail cirrus climate modelling.

Contrail cirrus supporting areas in model and observations [PDF]
, 2008 Contrails form and persist dependent on the surrounding moisture, temperature and pressure fields and on fuel and aircraft specific variables. After formation, contrail persistence requires only supersaturation relative to ice.

Long-lived contrails and convective cirrus above the tropical tropopause [PDF]
Atmospheric Chemistry and Physics, 2017 This study has two objectives: (1) it characterizes contrails at very low temperatures and (2) it discusses convective cirrus in which the contrails occurred.

Understanding the role of contrails and contrail cirrus in climate change: a global perspective [PDF]
Atmospheric Chemistry and PhysicsGlobally, 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.

Modelling and evaluation of aircraft contrails for 4-dimensional trajectory optimisation [PDF]
, 2015 Contrails and aircraft-induced cirrus clouds are reputed being the largest components of aviation-induced global warming, even greater than carbon dioxide (CO2) exhaust emissions by aircraft.

Aviation contrail climate effects in the North Atlantic from 2016 to 2021 [PDF]
Atmospheric Chemistry and Physics, 2022 Around 5 % of anthropogenic radiative forcing (RF) is attributed to aviation CO2 and non-CO2 impacts. This paper quantifies aviation emissions and contrail climate forcing in the North Atlantic, one of the world's busiest air traffic corridors, over 5 ...

A Lagrangian analysis of ice-supersaturated air over the North Atlantic [PDF]
, 2013 Understanding the nature of air parcels that exhibit ice-supersaturation is important because they are the regions of potential formation of both cirrus and aircraft contrails, which affect the radiation balance.

Sensitivity of radiative properties of persistent contrails to the ice water path [PDF]
Atmospheric Chemistry and Physics, 2012 The dependence of the radiative properties of persistent linear contrails on the variability of their ice water path is assessed in a two-stream radiative transfer model.
