This work presents an analysis of the physical properties of sub-micrometer
aerosol particles measured at the high Arctic site Villum Research Station,
Station Nord (VRS), northeast Greenland, between July 2010 and February 2013.
The study focuses on particle number concentrations, particle number size
distributions and the occurrence of new particle formation (NPF) events and
their seasonality in the high Arctic, where observations and characterization
of such aerosol particle properties and corresponding events are rare and
understanding of related processes is lacking.<br><br>A clear accumulation mode was observed during the darker months from October
until mid-May, which became considerably more pronounced during the prominent
Arctic haze months from March to mid-May. In contrast, nucleation- and
Aitken-mode particles were predominantly observed during the summer months.
Analysis of wind direction and wind speed indicated possible contributions of
marine sources from the easterly side of the station to the observed
summertime particle number concentrations, while southwesterly to westerly
winds dominated during the darker months. NPF events lasting from hours to
days were mostly observed from June until August, with fewer events observed
during the months with less sunlight, i.e., March, April, September and October.
The results tend to indicate that ozone (O<sub>3</sub>) might be weakly
anti-correlated with particle number concentrations of the nucleation-mode
range (10–30 nm) in almost half of the NPF events, while no positive
correlation was observed. Calculations of air mass back trajectories using
the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model
for the NPF event days suggested that the onset or interruption of events
could possibly be explained by changes in air mass origin. A map of event
occurrence probability was computed, indicating that southerly air masses
from over the Greenland Sea were more likely linked to those events. |
