Fig. 5 — Aerosol particle number concentrations. Measured and modelled particle number concentrations at the Station for Measuring Ecosystem-Atmosphere Relations II (SMEAR II) from the periods 15–25 May 2013 and 15 April to 5 May 2014. Panels a and b show the measured and modelled particle number size distributions respectively. Panels c, d and e show the measured and modelled median diurnal cycles of particle number concentrations in the nucleation mode (3–25 nm in diameter, PN_{3–25 nm}), Aitken mode (25–100 nm in diameter, PN_{25–100 nm}), and accumulation mode (100–1000 nm in diameter, PN_{100-1000 nm}) respectively. The shaded areas illustrate the measured (grey) and modelled (pink) ranges within the 25th and 75th percentiles. The particle number size distributions were measured with a differential mobility particle sizer (DMPS)
