Abstract. Powering aircraft by sustainable aviation fuels (SAFs) is a pathway to reduce the climate impact of lowering lifecycle CO2 emissions and reducing ice crystal numbers radiative forcing from contrails. While effect SAF blends on contrails has been measured previously, here we present novel measurements particle emission 100 % combustion. During ECLIF3 (Emission CLimate Impact alternative Fuels) campaign, collaboration between Deutsches Zentrum für Luft- und Raumfahrt (DLR), Airbus,...
Abstract. Nitrogen oxides, emitted from air traffic, are of concern due to their impact on climate by changing atmospheric ozone and methane levels. Using the DLR research aircraft Falcon, total reactive nitrogen (NOy) measurements were carried out at high altitudes characterize emissions in fresh exhaust latest generation Rolls-Royce Trent XWB-84 engine aboard long-range Airbus A350-941 aircraft. The different thrust settings, monitored terms combustor inlet temperature, pressure, fuel...
Abstract. In order to reduce aviation's CO2 emissions and comply with current climate targets, the European Union plans a mandatory quota of 2 % sustainable aviation fuel (SAF) by 2025, rising up ≥70 SAF 2050. addition reduction life cycle emissions, use can also have positive impact on particle contrail properties. this study we present observations from ECLIF3 (Emission CLimate Impact alternative Fuels) aircraft campaign, which investigated exhaust characteristics an Airbus A350-941...
Alternative aviation fuels represent a promising approach to reduce contrails climate effect. In the frame of VOLCAN (“VOL avec Carburants Alternatifs Nouveaux”) project (DGAC funding, collaboration with AIRBUS, Safran Aircraft Engines and DLR, financed by Neofuels), influence Sustainable Fuels (SAF) composition on exhaust plumes emission, therefore contrails, is investigated using 1D detailed microphysical code MoMiE (Modèle Microphysique pour Effluents)...

A worldwide increase in the number of people and areas affected by disasters has led to more approaches that focus on integration local knowledge into disaster risk reduction processes. The research at hand shows a method for formalizing this via sketch maps context flooding. Sketch Map Tool enables not only visualization analyses OpenStreetMap data quality but also communication results these an understandable way. Since tool will be open-source several are made automatically, offers...
Abstract. Nitrogen oxides, emitted from air traffic, are of concern due to their impact on climate by changing atmospheric ozone and methane levels. Using the DLR research aircraft Falcon, total reactive nitrogen (NOy) in-flight measurements were carried out at high altitudes characterize emissions in fresh exhaust latest-generation Rolls-Royce Trent XWB-84 engine aboard long-range Airbus A350-941 during ECLIF3 (Emission CLimate Impact alternative Fuels 3) experiment. The different thrust...
Ambient weather conditions strongly impact contrail formation and persistence. The implementation of avoidance mitigation strategies, therefore, requires regional altitude-dependent information on the frequency occurrence. To this end, we have developed a method to quantify potential cover based 10 years high-resolution reanalysis climatology data from European Center for Medium-Range Weather Forecast (ECMWF). We use Schmidt–Appleman threshold temperature additionally select thresholds...

In order to reduce aviation’s CO2 emissions and comply with current climate targets, the European Union plans a mandatory quota of 2 % sustainable aviation fuel (SAF) by 2025, rising up ≥ 70 SAF 2050. addition reduction life cycle CO2-emissions use can also have positive impact on particle contrail properties. this study we present observations from ECLIF3 (Emission CLimate Impact alternative Fuels) aircraft campaign, which investigated exhaust characteristics an Airbus A350-941...
Convective processes play a critical role in the atmosphere’s energy balance. In high updraft regimes, turbulent and diabatic redistribute moisture, heat, aerosols, which lead to cloud formation affecting radiation budget of atmosphere. During HALO airborne CIRRUS-HL mission summer 2021, outflow convective system over Northern Italy was probed at different altitudes. The had an overshooting top accompanied by lightning icing conditions. A suit in-situ (aerosol, probes, trace gases)...
Analyzing the formation of contrails on emissions from most recent generation aircraft engines is key to understand climate impact aviation. As for conventional Rich-Quench-Lean contrail ice crystals mainly form a high number emitted soot particles, question arises which and how many particles are activated during process if strongly reduced through Lean Combustion technology. The ecoDemonstrator experiment collaboration between Boeing, GE, NASA, DLR other international partners took place...

The decarbonization of air transportation requires novel propulsion concepts in order to replace fossil kerosene powered gas turbines. Within various options, H2 based is one the most promising candidates, at least for regional and short haul routes. However, despite potential reduce CO2 emissions zero, those aircraft can still have a significant climate impact due increased contrail formation caused by higher water emission when using as propellant. In understand changes traffic, it crucial...
