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 ...

Characteristics and effects of aerosols during blowing snow events in the central Arctic

Julia Schmale, Benjamin Jérémy Laurent Heutte, Jakob Boyd Pernov, Nora Bergner, Michael Lonardi, Jian Wang, Ivo Fabio Beck, Hélène Paule Angot

Sea salt aerosol (SSaer) significantly impacts aerosol-radiation and aerosol-cloud interactions, and sublimated blowing snow is hypothesized to be an important SSaer source in polar regions. Understanding blowing snow and other wind-sourced aerosols’ clima ...

Calving-driven fjord dynamics resolved by seafloor fibre sensing

Julia Schmale

Interactions between melting ice and a warming ocean drive the present-day retreat of tidewater glaciers of Greenland1–3, with consequences for both sea level rise4 and the global climate system5. Controlling glacier frontal ablation, these ice–ocean inter ...

Data-driven modeling of environmental factors influencing Arctic methanesulfonic acid aerosol concentrations

Julia Schmale, Jakob Boyd Pernov

Natural aerosol components such as particulate methanesulfonic acid (MSA p) play an important role in the Arctic climate. However, numerical models struggle to reproduce MSA p concentrations and seasonality. Here we present an alternative data-driven metho ...

Insights of aerosol-precipitation nexus in the central Arctic through CMIP6 climate models Check for updates

Julia Schmale

The Arctic is experiencing heightened precipitation, affected by aerosols impacting rainfall and snowfall. However, sparse aerosol observations in the central Arctic cryosphere contribute to uncertainties in simulating aerosol-precipitation two-way interac ...

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 ...

Ice nucleating particle sources and transports between the Central and Southern Arctic regions during winter cold air outbreaks

Julia Schmale, Ivo Fabio Beck

Ice nucleating particles (INPs) initiate ice formation, affecting the liquid versus ice distribution and radiative properties of clouds. INPs have been measured around the Arctic, but few INP concentration measurements have been reported for air during mov ...

Aerosol, trace gas and meteorological data measured at the University of Alaska Fairbanks Farm site in Fairbanks, Alaska during the Alaskan Layered Pollution And Chemical Analysis (ALPACA)-2022 field study

Julia Schmale

These measurements were made as part of the Alaskan Layered Pollution And Chemical Analysis (ALPACA)-2022 field study (https://alpaca.community.uaf.edu/alpaca-field-study/), which investigated air pollution under dark and cold conditions in Fairbanks, Alas ...

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 ...

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 ...
