Meteorological observations and condensation nuclei measurements at the Princess Elisabeth Antarctica Research Station during three austral summers
For three austral summer seasons (2013-2016, each from December to February) aerosol particles arriving at the Belgian Antarctic research station Princess Elisabeth (PE), in Dronning Maud Land in East Antarctica were characterized. This included number concentrations of total aerosol particles (N[CN...

For three austral summer seasons (2013-2016, each from December to February) aerosol particles arriving at the Belgian Antarctic research station Princess Elisabeth (PE), in Dronning Maud Land in East Antarctica were characterized. This included number concentrations of total aerosol particles (N[CN]) and cloud condensation nuclei (N[CCN]), the particle number size distribution (PNSD), the aerosol particle hygroscopicity and the influence of the air mass origin on N[CN] and N[CCN]. In general N[CN] was found to range from 40 to 6700 cm^-3 with a median of 333 cm^-3, while N[CCN] was found to cover a range between less than 10 and 1300 cm^-3 for supersaturations (SS) between 0.1 and 0.7%. It is shown that the aerosol is Aitken mode dominated, being characterized by a significant amount of small, and therefore likely secondarily formed aerosol particles, with 94% and 36% of the aerosol particles smaller than 90 nm and ~35 nm, respectively. Measurements of the basic meteorological parameters as well as the history of the air masses arriving at the measurement station indicate that the station is influenced by both, marine air masses originating from the Southern Ocean and coastal areas around Antarctica (marine events - MEs) and continental air masses (continental events - CEs).
