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 ...
2024A full year of aerosol size distribution data from the central Arctic under an extreme positive Arctic Oscillation: insights from the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada, Federico Bianchi
The Arctic environment is rapidly changing due to accelerated warming in the region. The warming trend is driving a decline in sea ice extent, which thereby enhances feedback loops in the surface energy budget in the Arctic. Arctic aerosols play an importa ...
2023Low ozone dry deposition rates to sea ice during the MOSAiC field campaign: Implications for the Arctic boundary layer ozone budget
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot
Dry deposition to the surface is one of the main removal pathways of tropospheric ozone (O3). We quantified for the first time the impact of O3 deposition to the Arctic sea ice on the planetary boundary layer (PBL) O3 concentration and budget using year-ro ...
2023Thermal Conductivity of Snow on Arctic Sea Ice
Henning Löwe, Marc Schneebeli Zeugin, David Nicholas Wagner
Snow significantly impacts the seasonal growth of Arctic sea ice due to its thermally insulating properties. Various measurements and parametrizations of thermal properties exist, but an assessment of the entire seasonal evolution of thermal conductivity a ...
2023The Marginal Ice Zone as a dominant source region of atmospheric mercury during central Arctic summertime
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot
Atmospheric gaseous elemental mercury (GEM) concentrations in the Arctic exhibit a clear summertime maximum, while the origin of this peak is still a matter of debate in the community. Based on summertime observations during the Multidisciplinary drifting ...
2023Overview of the MOSAiC expedition—Atmosphere
Julia Schmale, Ivo Fabio Beck, Radiance Flore Aurore Calmer, Michael Lonardi, Hélène Paule Angot, Markus Frey, Thomas Krumpen
With the Arctic rapidly changing, the needs to observe, understand, and model the changes are essential. To support these needs, an annual cycle of observations of atmospheric properties, processes, and interactions were made while drifting with the sea ic ...
2022Wind Transport of Snow Impacts Ka- and Ku-band Radar Signatures on Arctic Sea Ice
Marc Schneebeli Zeugin, David Nicholas Wagner
Wind transport alters the snow topography and microstructure on sea ice through snow redistribution controlled by deposition and erosion. The impact of these processes on radar signatures is poorly understood. Here, we examine the effects of snow redistrib ...
2022Annual cycle observations of aerosols capable of ice formation in central Arctic clouds
The Arctic is warming faster than anywhere else on Earth, prompting glacial melt, permafrost thaw, and sea ice decline. These severe consequences induce feedbacks that contribute to amplified warming, affecting weather and climate globally. Aerosols and cl ...
2022Fluorescent aerosols in the Arctic: Seasonality and sources
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Hélène Paule Angot, Margarida Teles Nogueira Rolo
Aerosol-cloud interactions play an important role in regulating the Arctic climate. However, cloud formation processes in the Arctic remain poorly understood and information on aerosol properties in this environment are insufficient, especially during pola ...
2022What are the likely changes in mercury concentration in the Arctic atmosphere and ocean under future emissions scenarios?
Arctic mercury (Hg) concentrations respond to changes in anthropogenic Hg emissions and environmental change. This manuscript, prepared for the 2021 Arctic Monitoring and Assessment Programme Mercury Assessment, explores the response of Arctic Ocean Hg con ...
