The global variation in ice-nucleating particle (INP) concentrations is an important modulator
of the cloud-phase feedback, where the albedo of mixed-phase clouds increases in a …

Reactive trace gas emissions from the polar oceans are poorly characterized, even though
their effects on atmospheric chemistry and aerosol formation are crucial for assessing …

Polar oceans and sea ice cover 15% of the Earth's ocean surface, and the environment is
changing rapidly at both poles. Improving knowledge on the interactions between the …

The MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate)
expedition was the largest Arctic field campaign ever conducted. MOSAiC offered the unique …

Abstract Changes in the availability of a subset of aerosol known as ice-nucleating particles
(INPs) can substantially alter cloud microphysical and radiative properties. Despite very …

Supercooled liquid clouds are ubiquitous over the Southern Ocean (SO), even to
temperatures below− 20° C, and comprise a large fraction of the marine boundary layer …

The sources and abundance of ice-nucleating particles (INPs) that initiate cloud ice
formation remain understudied, especially in the Southern Hemisphere. In this study, we …

The goal of the Sea2Cloud project is to study the interplay between surface ocean
biogeochemical and physical properties, fluxes to the atmosphere, and ultimately their …

Isoprene is a key trace component of the atmosphere emitted by vegetation and other
organisms. It is highly reactive and can impact atmospheric composition and climate by …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …
