Figure 7a illustrates the averaged GF-PDFs in the newly forming ML. A first compar- compar-ison between the two dry sizes probed by the WHOPS reveals a strong resemblance of the GF-PDF shapes for GF > 1.5, except for a small shift towards larger GFs for

Figure 10 does not show a large inter-annual variability of the air masses circulation over the three sites ; the main dif- ferences are observed over the Cinzana site in summer

Overall, mass transfer effects in hygroscopic measurements of ambient particles and laboratory generated particles are possible if the particles are not allowed to have sufficient

In this study, we analyzed number concentration and size distribution of aerosol particles, together with the mass concentration and chemical composition of UFPs and PM 1

Measurements of aerosol chemical composition and aerosol optical depth in the Nepal Himalaya have clearly shown the build up of aerosols in the pre-monsoon season during the winter

The reported method decouples any change in the charge transfer properties of the particles from the measurement signal, so the e ff ect of particle phase changes on bounce alone can

The change of phase can be clearly seen in the bounce dia- gram of 115 nm (mobility size), ammonium sulfate (Fig. 4), where the fraction of the bounced particles reduce almost with
