Aircraft-produced contrail cirrus clouds contribute to anthropogenic climate change.
Observational data sets and modelling approaches have become available that clarify …

Contrail cirrus account for the major share of aviation's climate impact. Yet, the links between
jet fuel composition, contrail microphysics and climate impact remain unresolved. Here we …

Clouds and aerosols continue to contribute the largest uncertainty to estimates and
interpretations of the Earth's changing energy budget. This chapter focuses on process …

The climate impact of air traffic is to a large degree caused by changes in cirrus cloudiness
resulting from the formation of contrails. Contrail cirrus radiative forcing is expected to …

Sustainable aviation fuels can reduce contrail ice numbers and radiative forcing by contrail
cirrus. We measured apparent ice emission indices for fuels with varying aromatic content at …

Powering aircraft by sustainable aviation fuels (SAFs) is a pathway to reduce the climate
impact of aviation by lowering aviation lifecycle CO 2 emissions and by reducing ice crystal …

ML-CIRRUS: The Airborne Experiment on Natural Cirrus and Contrail Cirrus with the High-Altitude
Long-Range Research Aircraft HALO in: Bulletin of the American Meteorological Society …

Abstract During spring 2020, the COVID-19 pandemic caused massive reductions in
emissions from industry and ground and airborne transportation. To explore the resulting …

Emissions of aviation include CO 2, H 2 O, NO x, sulfur oxides, and soot. Many studies have
investigated the annual mean climate impact of aviation emissions. While CO 2 has a long …
