Radiative heating in contrail cirrus [PDF]
, 2010 We developed an effective model (within our contrail cirrus prediction model, CoCiP) which computes the radiative heating rate in both the longwave and shortwave spectral ranges.

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 ...

Upper-tropospheric slightly ice-subsaturated regions: frequency of occurrence and statistical evidence for the appearance of contrail cirrus [PDF]
Atmospheric Chemistry and Physics, 2023 Microphysical, optical, and environmental properties of contrail cirrus and natural cirrus were investigated by applying a new, statistically based contrail–cirrus separation method to 14.7 h of cirrus cloud measurements (sampling frequency 1 Hz, max ...

Aerospace, 2022 Ambient weather conditions strongly impact contrail formation and persistence. The implementation of contrail avoidance and mitigation strategies, therefore, requires regional and altitude-dependent information on the frequency of contrail occurrence. To

Selected topics on the interaction between cirrus clouds and embedded contrails [PDF]
Atmospheric Chemistry and Physics, 2012 Persistent contrails and natural cirrus clouds often coexist in the upper troposphere and contrails can be embedded within cirrus clouds. The present paper deals with some questions regarding the interaction of cirrus clouds and embedded contrails.

Air traffic and contrail changes over Europe during COVID-19: a model study [PDF]
Atmospheric Chemistry and Physics, 2021 The strong reduction of air traffic during the COVID-19 pandemic provides a unique test case for the relationship between air traffic density, contrails, and their radiative forcing of climate change.

Revisiting the Link Between Thunderstorms and Upper Tropospheric Water Vapor
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 24, 27 December 2023., 2023 Abstract As the Earth's temperatures continue to rise due to increasing greenhouse gases in the atmosphere, a large portion of the warming is due to positive feedbacks from increasing atmospheric water vapor or specific humidity (SH). Some of this water vapor in the boundary layer is transported via deep convection to the upper troposphere (as droplets

An automatic contrail tracking algorithm [PDF]
Atmospheric Measurement Techniques, 2010 A method designed to track the life cycle of contrail-cirrus using satellite data with high temporal and spatial resolution, from its formation to the final dissolution of the aviation-induced cirrus cloud is presented.

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 22, 27 November 2023., 2023 Abstract Aircraft measurements reveal ice supersaturation statistics in cirrus (ISSs) with broad maxima around ice saturation and pronounced variance. In this study, processes shaping ISSs in midlatitude and tropical upper tropospheric conditions are systematically investigated.
