Atmospheric reactive nitrogen and its dry deposition regimes under anthropogenic influence: Insights from intensive and long-term monitoring in Switzerland

Athanasios Nenes, Andrea Baccarini, Kalliopi Violaki, Ghislain Gilles Jean-Michel Motos

Excessive nitrogen deposition from anthropogenic activities poses significant challenges to ecosystems and air quality.1 The atmospheric deposition of ammonium and nitrate plays a critical role in regulating ecosystem productivity and driving particulate m ...

Observations of high-time-resolution and size-resolved aerosol chemical composition and microphysics in the central Arctic: implications for climate-relevant particle properties

Julia Schmale, Andrea Baccarini, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Nora Bergner, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada, Markus Frey

Aerosols play a critical role in the Arctic's radiative balance, influencing solar radiation and cloud formation. Limited observations in the central Arctic leave gaps in understanding aerosol dynamics year-round, affecting model predictions of climate-rel ...

Investigating processes influencing simulation of local Arctic wintertime anthropogenic pollution in Fairbanks, Alaska, during ALPACA-2022

Julia Schmale, Andrea Baccarini, Roman Pohorsky

Lagrangian tracer simulations are deployed to investigate processes influencing vertical and horizontal dispersion of anthropogenic pollution in Fairbanks, Alaska, during the Alaskan Layered Pollution and Chemical Analysis (ALPACA) 2022 field campaign. Sim ...

Anthropogenic organic aerosol in Europe produced mainly through second-generation oxidation

Andrea Baccarini

Exposure to anthropogenic atmospheric aerosol is a major health issue, causing several million deaths per year worldwide. The oxidation of aromatic hydrocarbons from traffic and wood combustion is an important anthropogenic source of low-volatility species ...

NATURE PORTFOLIO2025

Surface distributions and vertical profiles of trace gases (CO, O3, NO, NO2) in the Arctic wintertime boundary layer using low-cost sensors during ALPACA-2022

Julia Schmale, Andrea Baccarini, Roman Pohorsky

Electrochemical gas sensors (EGSs) have been used to measure the surface distributions and vertical profiles of trace gases in the wintertime Arctic boundary layer during the Alaskan Layered Pollution and Chemical Analysis (ALPACA) field experiment in Fair ...

COPERNICUS GESELLSCHAFT MBH2025

In situ vertical observations of the layered structure of air pollution in a continental high-latitude urban boundary layer during winter

Julia Schmale, Andrea Baccarini, Roman Pohorsky

Vertical in situ measurements of aerosols and trace gases were conducted in Fairbanks, Alaska, during winter 2022 as part of the Alaskan Layered Pollution and Chemical Analysis campaign (ALPACA). Using a tethered balloon, the study explores the dispersion ...

Temperature, humidity, and ionisation effect of iodine oxoacid nucleation

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

Iodine oxoacids are recognised for their significant contribution to the formation of new particles in marine and polar atmospheres. Nevertheless, to incorporate the iodine oxoacid nucleation mechanism into global simulations, it is essential to comprehend ...

Highly Hygroscopic Aerosols Facilitate Summer and Early‐Autumn Cloud Formation at Extremely Low Concentrations Over the Central Arctic Ocean

Julia Schmale, Andrea Baccarini

Arctic clouds are sensitive to atmospheric particles since these are sometimes in such low concentrations that clouds cannot always form under supersaturated water vapor conditions. This is especially true in the late summer, when aerosol concentrations ar ...

Equivalent black carbon concentration measured with an aethalometer AE33 during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini, Benjamin Jérémy Laurent Heutte

Equivalent black carbon (eBC) mass concentration was measured with a commercial aethalometer (model AE33, Magee Scientific, Berkeley, USA). Measurements were performed onboard of the Swedish icebreaker (I/B) Oden from August to September 2018 as part of th ...

Overview of the Alaskan Layered Pollution and Chemical Analysis (ALPACA) Field Experiment

Athanasios Nenes, Julia Schmale, Andrea Baccarini, Roman Pohorsky, Sukriti Kapur

The Alaskan Layered Pollution And Chemical Analysis (ALPACA) field experiment was a collaborative study designed to improve understanding of pollution sources and chemical processes during winter (cold climate and low-photochemical activity), to investigat ...
