Contrail Modeling and Simulation [PDF]
Annual Review of Fluid Mechanics, 2016 There is large uncertainty in the radiative forcing induced by aircraft contrails, particularly after they transform to cirrus. It has recently become possible to simulate contrail evolution for long periods after their formation. We review the main physical processes and simulation efforts in the four phases of contrail evolution, namely the jet ...

Properties of In-cirrus Contrails from Airborne Remote-sensing Data [PDF]
EPJ Web of ConferencesAviation impacts the Earth's energy balance through non-CO2 effects and emissions of exhaust gases and soot. Planes flying through cirrus clouds can create contrails that might affect the climate effect of these clouds.

A contrail cirrus prediction model [PDF]
Geoscientific Model Development, 2012 A new model to simulate and predict the properties of a large ensemble of contrails as a function of given air traffic and meteorology is described.

Monte Carlo Simulations in Aviation Contrail Study: A Review
Applied Sciences, 2022 This article provides a review of the role of stochastic approaches, in particular Monte Carlo calculations, in the study of aviation-induced contrails at different characteristic lengths, ranging from micrometers to the planetary scale. Pioneered in the

, 2002 A contrail (a term introduced for “condensation trail” in 1942 by British pilots) is a visible cloud forming behind aircraft, mainly due to water vapor emissions from the engines. Contrails were first observed behind propeller-driven aircraft in 1915 but form as well from the exhaust of jet engines in cold ambient air (Schumann 1996a).

, 2012 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

Contrails — a prototype of cirrus cloud studies since 80 years
Meteorologische Zeitschrift, 1997 The clouds often seen to be formed in the wake of aircraft are called condensation trails (Brewer 1946), contrails (Appleman 1953), or Kondensstreifen. Contrails form behind propeller-driven aircraft as well as behind jet aircraft.

Contrails and Their Dependence on Meteorological Situations
Applied SciencesContrails created by aircraft are a very hot topic today because they contribute to the warming of the atmosphere. Air traffic density is very high, and current forecasts predict a further significant increase.

Potential impact of contrails on solar energy gain [PDF]
Atmospheric Measurement Techniques, 2015 The effect of contrails on global short-wave radiation (sum of direct and downward diffuse solar radiation) and on solar energy gain was investigated. The study was performed during days with high contrail persistence and focused on situations where the ...

Energy Science &Engineering, EarlyView.This study investigates how iron particles burn across a wide size range, revealing late‐stage nanoparticle release and a previously unrecognised shift in combustion behaviour near 118 µm. High‐speed imaging, PMT diagnostics and SEM analyses have been conducted.
