Investigation of new particle formation mechanisms and aerosol processes at Marambio Station, Antarctic Peninsula
Understanding chemical processes leading to the formation of atmospheric aerosol particles is crucial to improve our capabilities in predicting the future climate. However, those mechanisms are still inadequately characterized, especially in polar regions. ...
COPERNICUS GESELLSCHAFT MBH2022Diurnal evolution of negative atmospheric ions above the boreal forest: from ground level to the free troposphere
At SMEAR II research station in Hyytiala, located in the Finnish boreal forest, the process of new particle formation and the role of ions has been investigated for almost 20 years near the ground and at canopy level. However, above SMEAR II, the vertical ...
COPERNICUS GESELLSCHAFT MBH2022Annual aerosol chemical composition retrieved from an aerosol mass spectrometer in the central Arctic
Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Hélène Paule Angot, Lubna Dada
The Arctic environment is transforming rapidly due to climate change, which induces several feedback processes such as retreating sea ice, changing atmospheric transport patterns and cloud formation. In addition, more local pollution due to shipping and re ...
2022Equivalent black carbon concentration in 10 minutes time resolution, measured in the Swiss container during MOSAiC 2019/2020
Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Lubna Dada
This dataset contains equivalent black carbon (eBC) concentrations, averaged to 10 min time resolution, measured during the year-long MOSAiC expedition from October 2019 to September 2020. The measurements were performed in the Swiss container on the D-dec ...
Pangaea2022Seasonal variation of airborne coarse and fluorescent particles
Julia Schmale, Ivo Fabio Beck, Nora Bergner, Hélène Paule Angot, Lubna Dada, Margarida Teles Nogueira Rolo
Coarse mode aerosols receive relatively little attention in Arctic atmospheric research compared to smaller aerosol populations. However, coarse mode particles have important implications for aerosol-radiation interactions as well as aerosol-cloud interact ...
2022Automated identification of local contamination in remote atmospheric composition time series
Jian Wang, Julia Schmale, Andrea Baccarini, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada
A common challenge of atmospheric measurements in remote environments is to identify pollution from nearby activities that interfere with the purpose of the observations. Pollution, particularly from combustion, typically reveals itself in enhanced particl ...
2022Aerosol formation and growth rates from chamber experiments using Kalman smoothing
Bayesian state estimation in the form of Kalman smoothing was applied to differential mobility analyser train (DMA-train) measurements of aerosol size distribution dynamics. Four experiments were analysed in order to estimate the aerosol size distribution, ...
2021Impact Of Warm Air Mass Intrusions On Atmospheric Chemistry And Microphysics
Julia Schmale, Andrea Baccarini, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada
Arctic winter is dominated by anthropogenic haze, while pollution transport from mid-latitudes decreases in summertime. As a result, aerosol concentrations reach a maximum in winter and drop to minimum in summer. What happens during the season transition, ...
2021Impact of warm air mass intrusions on atmospheric chemistry and microphysics: Observations during MOSAiC
Julia Schmale, Ivo Fabio Beck, Lubna Dada
Arctic winter is dominated by anthropogenic haze, while pollution transport from mid-latitudes decreases in summertime. As a result, aerosol concentrations reach a maximum in winter and drop to minimum in summer. What happens during the season transition, ...
2021Chemical and Microphysical State of the Central Arctic Atmosphere
Julia Schmale, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada
The Arctic is warming three times faster than the rest of the planet. Increased areas of open ocean and changes in atmospheric transport pathways affect the Arctic atmospheric chemical and microphysical state, which themselves can modulate cloud, precipita ...
