Atmospheric Adjustments to In Situ Cirrus Formation in Ice Supersaturated Regions
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.Abstract High‐level ice clouds exert a net warming on the climate system because their greenhouse effect outweighs their albedo effect. Focusing on in‐situ cirrus, their formation involves the conversion of upper‐tropospheric water vapor into ice crystals.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 2, 28 January 2026.Abstract Line‐shaped contrails formed behind aircraft can evolve into broadly spread and long‐living cirrus clouds under favorable conditions. These contrail‐cirrus contribute significantly to the aviation‐induced radiative forcing. While past modeling studies have examined contrail‐cirrus across various atmospheric and aircraft‐type dependent ...

Properties of individual contrails: a compilation of observations and some comparisons [PDF]
Atmospheric Chemistry and Physics, 2017 Mean properties of individual contrails are characterized for a wide range of jet aircraft as a function of age during their life cycle from seconds to 11.5 h (7.4–18.7 km altitude, −88 to −31 °C ambient temperature), based on a compilation of about 230 ...

Elementary GLOBE: To Spread or Not To Spread [PDF]
, 2008 A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Students will explore the difference between the three types of contrails, make observations of contrails outside, and record their observations ...

Aircraft induced contrail cirrus over Europe [PDF]
Meteorologische Zeitschrift, 2005 Condensation trails (contrails) and aircraft induced cirrus are nowadays a common feature at the mid latitude skies. Previously the impact of aircraft induced cirrus changes has been roughly estimated from observed decadal trends in cirrus cover but the direct attribution of observed cirrus changes to changes in aviation activity remains uncertain.

Contrail Observation Limitations Using Geostationary Satellites
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Contrails are a significant contributor to aviation's climate impact with an effective radiative forcing similar to that from aviation's CO2 ${\text{CO}}_{2}$ emissions, yet large uncertainties remain. Many observational contrail studies rely on data from a single sensor, in recent years increasingly from a geostationary imager, accepting ...

Regional and seasonal impact of hydrogen propulsion systems on potential contrail cirrus cover
Atmospheric Environment: XThe decarbonization of air transportation requires novel propulsion concepts in order to replace fossil kerosene powered gas turbines. Within various options, H2 based propulsion is one of the most promising candidates, at least for regional and short ...

Beyond Contrail Avoidance: Efficacy of Flight Altitude Changes to Minimise Contrail Climate Forcing
Aerospace, 2020 Contrail cirrus introduce a short-lived but significant climate forcing that could be mitigated by small changes in aircraft cruising altitudes. This paper extends a recent study to evaluate the efficacy of several vertical flight diversion strategies to

AGU Advances, Volume 6, Issue 6, December 2025.Abstract The challenge of distinguishing convective anvil cirrus from in situ cirrus has long limited the quantification of their distinct roles in regulating upper‐tropospheric moisture and modulating Earth's energy budget. In this study, we address this ambiguity by introducing a physically constrained classification framework that applies advanced ...

The impact of diurnal variations of air traffic on contrail radiative forcing [PDF]
, 2007 We combined high resolution aircraft flight data from the EU Fifth Framework Programme project AERO2k with analysis data from the ECMWF's integrated forecast system to calculate diurnally resolved 3-D contrail cover.
