Contrail properties over the eastern North Pacific from AVHRR data

Meteorologische Zeitschrift, 2005
An increase of air traffic over the North Pacific during the last 30 years has been accompanied by an increase in cirrus coverage. To help alleviate the uncertainty in the contribution of air traffic to the cirrus increase, an analysis of linear contrail

Observing long-lived longwave contrail forcing [PDF]

Atmospheric Measurement Techniques
Contrail microphysical simulations and climate simulations have indicated that contrail cirrus cause a substantial fraction of aviation's climate impact.

Emission metrics for quantifying regional climate impacts of aviation [PDF]

Earth System Dynamics, 2017
This study examines the impacts of emissions from aviation in six source regions on global and regional temperatures. We consider the NOx-induced impacts on ozone and methane, aerosols and contrail-cirrus formation and calculate the global and ...

Persistent Elevated Black Carbon Aerosol Layers in the Upper Troposphere and Its Linkage to Aircraft Emissions

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Altitude profiles of the mass concentrations of aerosol black carbon (BC) have been obtained,up to an altitude of 12 km, from in situ measurements over Hyderabad (17.47°N, 78.57°E, 557 m amsl;a tropical station in the central Indian peninsula), using three successive high altitude balloon ascents during winter and early summer seasons of 2023 ...

Understanding sources of contrail cirrus radiative forcing uncertainty using a new diagnostic contrail scheme for the UK Earth System Model

, 2023
Condensation trails (contrails) are aircraft-induced line-shaped high clouds, which may persist and grow to form contrail cirrus in ice supersaturated regions.

A 424 and 448 GHz Receiver for Aircraft Contrail Observations

IEEE Journal of Microwaves
Airplane produced contrail cirrus has a greenhouse effect in our atmosphere. It has an effect that is as much as or more than any other airplane emission such as airplane produced CO2 Karcher et al. 2018. With air traffic anticipated to increase into the

Key Gaps in Models' Physical Representation of Climate Intervention and Its Impacts

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 6, June 2025.
Abstract Solar radiation modification (SRM) is increasingly discussed as a potential method to ameliorate some negative effects of climate change. However, unquantified uncertainties in physical and environmental impacts of SRM impede informed debate and decision making.

A manually labeled contrail dataset from MSG/SEVIRI [PDF]

Earth System Science Data
Contrails – thin ice clouds formed by aircraft – are a major contributor to aviation-induced climate forcing, yet their observational characterization remains limited.

Sensitivity of surface temperature to radiative forcing by contrail cirrus in a radiative-mixing model

, 2017
. Earth's surface temperature sensitivity to radiative forcing (RF) by contrail cirrus and the related RF efficacy relative to CO2 are investigated in a one-dimensional idealized model of the atmosphere.

Contrail and Cirrus Observations over Europe from 6 Years of NOAA-AVHRR Data

, 2002
Thin ice clouds – cirrus and contrails – are analysed in a long-term 1 km data set from the Advanced Very High Resolution Radiometer (AVHRR). Here twice daily data received at DLR Oberpfaffenhofen covering most of Europe over the full lifetime of the ...
