Hemispheric differences in ozone across the stratosphere–troposphere exchange region Open
Ozone changes in the upper troposphere–lower stratosphere (UTLS) resulting from dynamical and chemical processes strongly affect the atmosphere's radiative forcing. This study analyzed intra- and inter-hemispheric ozone differences in the …
Reduced contrail radiative effect for fleets with low soot and water vapour emissions Open
Besides the goal of net-zero carbon dioxide (CO2) emissions, reducing aviation’s climate impact also involves addressing other forcing effects, particularly radiative forcing from contrails. Current understanding suggests that decreasing b…

Substantial aircraft contrail formation at low soot emission levels Open
Contrail cirrus are a major contributor to the climate forcing from aviation. Yet, the number of contrail ice crystals forming behind aircraft with modern lean-burn engines is unknown. Theory spans a five orders of magnitude range in ice c…
Designing a mission concept for atmospheric plume measurements during a rocket launch event Open
The frequency of space launches has increased dramatically as costs plummet and demand rises with the advent of use cases (such as mega constellations or larger-scale exploration). This increase in launch cadence is enabled by reusable lau…
Modeling the impact of aviation fuel hydrogen and sulfur content on contrail properties: insights and implications Open
Contrail cirrus represents the most significant warming component within the total aviation impact on climate, suspected to exceed even the effects of aviation CO2 emissions. It remains to be shown that regulating hydrogen and sulfur conte…
Modeling the formation of contrails produced by SAF emissions Open
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…
The influence of extratropical cross-tropopause mixing on the correlation between ozone and sulfate aerosol in the lowermost stratosphere Open
The chemical composition of the upper troposphere/lower stratosphere region (UTLS) is influenced by horizontal transport of air masses, vertical transport within convective systems and warm conveyor belts, rapid turbulent mixing, as well a…

Powering aircraft with 100 % sustainable aviation fuel reduces ice crystals in contrails Open
Powering aircraft by sustainable aviation fuels (SAFs) is a pathway to reduce the climate impact of aviation by lowering aviation lifecycle CO2 emissions and by reducing ice crystal numbers and radiative forcing from contrails. While the e…
Injection of water vapor into the stratosphere in a convective system above Europe – a measurement perspective Open
Convective processes play a critical role in the atmosphere’s energy balance. In high updraft regimes, turbulent and diabatic processes redistribute moisture, heat, and aerosols, which lead to cloud formation affecting the radiation budget…
The influence of extratropical cross-tropopause mixing on the correlation between ozone and sulfate aerosol in the lowermost stratosphere Open
The composition of the upper troposphere/lower stratosphere region (UTLS) is influenced by long-range or regional transport in the troposphere and stratosphere, vertical transport within convective systems and warm conveyor belts, rapid tu…

Redistribution of total reactive nitrogen in the lowermost Arctic stratosphere in winter 2015/2016: In-situ observations of nitrification, denitrification and particulate nitrate Open
The Arctic winter 2015/2016 was characterized by extremely low temperatures in the stratosphere and by a very strong polar vortex, accompanied by extended fields of Polar Stratospheric Clouds. During this winter, aircraft-based measurement…
Investigating the radiative effect of Arctic cirrus measured in situ during the winter 2015–2016 Open
