Characteristics and sources of fluorescent aerosols in the central Arctic Ocean
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Nora Bergner, Oliver Müller, Alireza Moallemi, Hélène Paule Angot, Markus Frey, Margarida Teles Nogueira Rolo
The Arctic is sensitive to cloud radiative forcing. Due to the limited number of aerosols present throughout much of the year, cloud formation is susceptible to the presence of cloud condensation nuclei and ice nucleating particles (INPs). Primary biologic ...
2024Reducing Aerosol Forcing Uncertainty by Combining Models With Satellite and Within-The-Atmosphere Observations: A Three-Way Street
Aerosol forcing uncertainty represents the largest climate forcing uncertainty overall. Its magnitude has remained virtually undiminished over the past 20 years despite considerable advances in understanding most of the key contributing elements. Recent wo ...
AMER GEOPHYSICAL UNION2023Polar oceans and sea ice in a changing climate
Julia Schmale, Hélène Paule Angot, Jenny Thomas
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 atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmospher ...
2023Arctic warming by abundant fine sea salt aerosols from blowing snow
Jian Wang, Julia Schmale, Nora Bergner, Xin Yang, Markus Frey
The Arctic warms nearly four times faster than the global average, and aerosols play an increasingly important role in Arctic climate change. In the Arctic, sea salt is a major aerosol component in terms of mass concentration during winter and spring. Howe ...
2023Untangling the influence of Antarctic and Southern Ocean life on clouds
Julia Schmale, Hélène Paule Angot, Jenny Thomas, Markus Frey
Polar environments are among the fastest changing regions on the planet. It is a crucial time to make significant improvements in our understanding of how ocean and ice biogeochemical processes are linked with the atmosphere. This is especially true over A ...
2023Role of sesquiterpenes in biogenic new particle formation
Andrea Baccarini, Imad El Haddad, Lubna Dada, Federico Bianchi
Biogenic vapors form new particles in the atmosphere, affecting global climate. The contributions of monoterpenes and isoprene to new particle formation (NPF) have been extensively studied. However, sesquiterpenes have received little attention despite a p ...
2023Multi-campaign ship and aircraft observations of marine cloud condensation nuclei and droplet concentrations
In-situ marine cloud droplet number concentrations (CDNCs), cloud condensation nuclei (CCN), and CCN proxies, based on particle sizes and optical properties, are accumulated from seven field campaigns: ACTIVATE; NAAMES; CAMP(2)EX; ORACLES; SOCRATES; MARCUS ...
NATURE PORTFOLIO2023Measurements of aerosol microphysical and chemical properties in the central Arctic atmosphere during MOSAiC
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Hélène Paule Angot, Lubna Dada
The Arctic environment is transforming rapidly due to climate change. Aerosols’ abundance and physicochemical characteristics play a crucial, yet uncertain, role in these changes due to their influence on the surface energy budget through direct interactio ...
2023Aerosol microphysics and chemical composition in the central Arctic atmosphere during the MOSAiC expedition
Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Nora Bergner, Hélène Paule Angot, Lubna Dada
The Arctic environment is transforming rapidly due to climate change. Aerosols’ abundance and physicochemical characteristics play a crucial, yet uncertain, role in these changes due to their influence on the surface energy budget, and aerosol properties a ...
2023Highly Active Ice‐Nucleating Particles at the Summer North Pole
The amount of ice versus supercooled water in clouds is important for their radiative properties and role in climate feedbacks. Hence, knowledge of the concentration of ice-nucleating particles (INPs) is needed. Generally, the concentrations of INPs are fo ...
