Evolution of the aerosol size distribution under laser illumination.
(a) Aerosol size distribution between 250 and 900 nm during both reference and active periods measured by the Grimm optical particle sizer and concentration of 25–300 nm particles measured by the Nanocheck (column centered at the mean diameter 80 nm); (b) Corresponding relative increase induced by the laser; (c) Dry particle size distribution (total mass detected by the AMS, calculated as the sum of nitrate, sulfate, organics, ammonium and chloride) during both reference and active periods and (d) Corresponding relative increase induced by the laser. Dva is the vacuum aerodynamic diameter. Stars denote size classes where the effect of the laser is statistically significant (α ≤ 0.01, see text for details). Error bars correspond to one standard deviation.
