On the Radiative Forcing by Contrails
TL;DR: In this paper, a parametric study of the instantaneous radiative impact of contrails is presented using three different radiative transfer models for a series of model atmospheres and cloud parameters, including tropical, mid-latitude, and subarctic summer and winter atmospheres.

EU ETS versus CORSIA – A critical assessment of two approaches to limit air transport's CO2 emissions by market-based measures
TL;DR: In this paper, the authors analyze and compare two CO 2 trading schemes for aviation from an environmental and competition perspective: the EU Emissions Trading Scheme (EU ETS) and the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA).

TL;DR: In this article, the authors show that although the emissions targets for aviation are in line with the overall goals of the Paris Agreement, there is a high likelihood that the climate impact of aviation will not meet these goals.
Journal ArticleDOI
The contribution of carbon dioxide emissions from the aviation sector to future climate change
TL;DR: In this article, the authors used the compact Earth system model OSCARv2.2 to assess the climate impact of present and future civil aviation carbon dioxide (CO2) emissions.

TL;DR: In this article, the authors provided experimental evidence that burning low aromatic sustainable aviation fuel can result in a 50 to 70% reduction in soot and ice number concentrations and an increase in ice crystal size.

On the effect of stage length on the efficiency of air transport
TL;DR: In this article, an analytic model has been developed from first principles, with closure provided by data from existing aircraft, to allow an accurate estimate of the potential benefits, and their influence is quantified.
Journal ArticleDOI
Numerical simulations of homogeneously nucleated natural cirrus and contrail-cirrus. Part 2: Interaction on local scale
TL;DR: In this article, the interaction of a pre-existing contrail-cirrus and natural cirrus formed by homogeneous nucleation is studied over up to ten hours by means of a LES model equipped with a Lagrangian ice microphysics module.
System Analysis for Future Long-Range Operation Concepts
TL;DR: In this paper, a global analysis of all Airbus A330 and Boeing 777 flights served in 2007 is performed, defining fuel-optimum intermediate airports wherever possible. But this analysis is limited to a single mission, depending mainly on aircraft design range and the geographic location of the refueling point with regards to origin and destination.

Air traffic simulation in chemistry-climate model EMAC 2.41: AirTraf 1.0
Hiroshi Yamashita,Volker Grewe,Volker Grewe,Patrick Jöckel,Florian Linke,Martin Schaefer,Daisuke Sasaki +6 more
TL;DR: AirTraf (version 1.0) that performs global air traffic simulations, including effects of local weather conditions on the emissions is introduced and a large reduction in the number of function evaluations can be achieved with only a small decrease in the accuracy.
Journal ArticleDOI
Dimension of aircraft exhaust plumes at cruise conditions: effect of wake vortices
TL;DR: In this article, the dispersion of aircraft emissions during the vortex phase is studied using a 3-D LES model with Lagrangian particle tracking, and the tracer dilution and plume extent is studied for a variety of ambient and aircraft parameters until aircraft-induced effects have ceased.
