disc-re/Contrail-Statistics: Contrail Statistics Tool
, 2022 This analysis tool evaluates the atmospheric contrail formation conditions based on ECMWF ERA-5 Reanalysis data and helps to obtain an overview of the frequency of contrail formation over the last 10 years at different altitudes, seasons and ...

The evolution of microphysical and optical properties of an A380 contrail in the vortex phase [PDF]
Atmospheric Chemistry and Physics, 2012 A contrail from a large-body A380 aircraft at cruise in the humid upper troposphere has been probed with in-situ instruments onboard the DLR research aircraft Falcon.

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 ...

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.

On contrail climate sensitivity [PDF]
Geophysical Research Letters, 2005 In equilibrium climate change simulations with a global climate model we estimate the climate sensitivity parameter to contrail cirrus to be 0.43 K/(Wm−2), only about 60% of the corresponding value for a CO2 forcing. The spatial pattern of the surface temperature response is much smoother than the forcing pattern of contrails with little correlation ...

Observations of microphysical properties and radiative effects of a contrail cirrus outbreak over the North Atlantic [PDF]
Atmospheric Chemistry and Physics, 2023 Contrail cirrus constitute the largest radiative forcing (RF) component to the total aviation effect on climate. However, the microphysical properties and radiative effects of contrail cirrus and natural cirrus clouds in the same meteorological ...

Aircraft type influence on contrail properties [PDF]
Atmospheric Chemistry and Physics, 2013 The investigation of the impact of aircraft parameters on contrail properties helps to better understand the climate impact from aviation. Yet, in observations, it is a challenge to separate aircraft and meteorological influences on contrail formation ...

Long-term upper-troposphere climatology of potential contrail occurrence over the Paris area derived from radiosonde observations [PDF]
Atmospheric Chemistry and Physics, 2023 Condensations trails (or contrails) that form behind aircraft have been of climatic interest for many years; yet, their radiative forcing is still uncertain.

Benchmarking and improving algorithms for attributing satellite-observed contrails to flights [PDF]
Atmospheric Measurement TechniquesCondensation 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 ...
