The summertime Arctic lower troposphere is a relatively pristine background aerosol
environment dominated by nucleation and Aitken mode particles. Understanding the …

Motivated by increasing levels of open ocean in the Arctic summer and the lack of prior
altitude-resolved studies, extensive aerosol measurements were made during 11 flights of …

A first regional assessment of the impact of shipping emissions on air pollution in the
Canadian Arctic and northern regions was conducted in this study. Model simulations were …

Abstract The Vertical City Weather Generator (VCWG) is a computationally efficient urban
microclimate model developed to predict temporal and vertical variation of potential …

The influence of roof-edge roughness elements on airflow, heat transfer, and street-level
pollutant transport inside and above a two-dimensional urban canyon is analyzed using an …

Decreasing sea ice and increasing marine navigability in northern latitudes have changed
Arctic ship traffic patterns in recent years and are predicted to increase annual ship traffic in …

Formic and acetic acid are ubiquitous and abundant in the Earth's atmosphere and are
important contributors to cloud water acidity, especially in remote regions. Their global …

Large-eddy simulations are used to investigate the influence of a horizontal frontal zone,
represented by a stationary uniform background horizontal temperature gradient, on the …

Melt pond formation is a seasonal pan-Arctic process. During the thawing season, melt
ponds may cover up to 90% of the Arctic first-year sea ice (FYI) and 15 to 25% of the multi …

Aircraft measurements are used to characterize properties of clear-air turbulence in the
lower Arctic troposphere. For typical vertical resolutions in general circulation models, there …
