Assessing the importance of nitric acid and ammonia for particle growth in the polluted boundary layer

Andrea Baccarini, Imad El Haddad, Lubna Dada, Houssni Lamkaddam

Aerosols formed and grown by gas-to-particle processes are a major contributor to smog and haze in megacities, despite the competition between growth and loss rates. Rapid growth rates from ammonium nitrate formation have the potential to sustain particle ...

A 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 ...

Aerosol source identification in the spring and summertime central Arctic Ocean using high-resolution mass spectrometry during MOSAiC

Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Imad El Haddad, Jakob Boyd Pernov, Hélène Paule Angot, Lubna Dada

The Arctic region is experiencing considerable changes and is warming at a rate three to four times as fast as the rest of the world. Aerosols, which can be from natural or anthropogenic sources, locally emitted or long-range transported, play a crucial ro ...
