It has been claimed that hydrogen aviation may still significantly contribute to global warming through jets contrails, as hydrogen jets produce more contrails than jets fueled with kerosene.

This chapter discusses how atmospheric scientists respond to challenging belief narratives, particularly the chemtrail theory. It starts with the work and legacy of the Weather Guys radio program at Wisconsin Public Radio presented by Steve A. Ackerman and Jonathan E. Martin.

Synoptic and microphysical lifetime constraints for contrails
Atmospheric Chemistry and Physics. Contrail lifetime is constrained mainly by the sedimentation of ice crystals into lower levels that are subsaturated, by the blowing out of the ice crystals from the parent ice-supersaturated regions (ISSRs) as a result of the (horizontal) wind and by ...

. Contrails can last for many hours in the sky if they form in ice supersaturated regions (ISSRs). Contrail formation is possible once the ambient air is sufficiently moist and cold (below −40 °C).

On the Weather Impact of Contrails: New Insights from Coupled ICON–CoCiP Simulations
Atmospheric Chemistry and Physics. Contrail forecasts typically neglect feedbacks with the atmosphere. Here, we couple the Contrail Cirrus Prediction model (CoCiP) with the global Icosahedral Non-hydrostatic (ICON) numerical weather model in a two-way mode accounting for contrail ...

Cloud computing infrastructures support dynamical and flexible access to computational, network and storage resources. To date, several disjoint industrial and academic technologies provide infrastruc- ture level access to Clouds. Especially for industrial platforms, the evolu- tion of de-facto standards goes together with worries about user lock-in to

Assessing the Environmental Impact of Aircraft/Engine Integration with Respect to Contrails
Journal of Engineering For Gas Turbines and PowerIn recent years, the radiative forcing of aircraft contrails and aircraft-induced contrail cirrus have been highlighted as a serious short-term climate impact of the aviation industry.
