Global aviation operations contribute to anthropogenic climate change via a complex set of
processes that lead to a net surface warming. Of importance are aviation emissions of …

Global air transportation has grown rapidly in the past decade until the recent coronavirus
pandemic. Previous research has demonstrated that particulate matter (PM) emissions from …

Sustainable aviation fuel (SAF) can reduce aviation's CO2 and non-CO2 impacts. We
quantify the change in contrail properties and climate forcing in the North Atlantic resulting …

Around 5% of anthropogenic radiative forcing (RF) is attributed to aviation CO 2 and non-CO
2 impacts. This paper quantifies aviation emissions and contrail climate forcing in the North …

The climate forcing of contrails and induced-cirrus cloudiness is thought to be comparable to
the cumulative impacts of aviation CO2 emissions. This paper estimates the impact of …

The contribution of aircraft operations to ambient ultrafine particle (UFP) concentration at
and around airports can be significant. This review article considers the volatile and non …

The strong reduction of air traffic during the COVID-19 pandemic provides a unique test case
for the relationship between air traffic density, contrails, and their radiative forcing of climate …

In order to reduce aviation's CO 2 emissions and comply with current climate targets, the
European Union plans a mandatory quota of 2% sustainable aviation fuel (SAF) by 2025 …

The COVID‐19 pandemic led to a 72% reduction of air traffic over Europe in March–August
2020 compared to 2019. Modeled contrail cover declined similarly, and computed mean …

Aircraft contrails, formed largely on soot particles in current flights, are important for
aviation's non-CO2 climate impact. Here we show that the activation of nonvolatile soot …
