Observations of the aerosol particle number concentration in the marine boundary layer over the south-eastern Baltic Sea
Continuous measurements of the aerosol particle number concentration (PNC) in the size range from 4.5 nm to 2 μm were performed at the Preila marine background site during 2008–2009. The concentration maxima in summer was twice the average (2650±850 cm-3). A trajectory-based approach was applied for...
