We have investigated the formation of cloud droplets under pyro-convective conditions using a cloud parcel model with detailed spectral microphysics and with the κ-Köhler model approach for effic...
Spatio-temporal variability and principal components of the particle number size distribution in an urban atmosphere
Spatio-temporal variability particle number size distribution urban atmosphere
2009/5/15
A correct description of fine (diameter <1 μm) and ultrafine (<0.1 μm) aerosol particles in urban areas is of interest for particle exposure assessment but also basic atmospheric research. We examined...

On the time-averaging of ultrafine particle number size spectra in vehicular plumes
time-averaging ultrafine particle size spectra vehicular plumes
2009/1/16
Ultrafine vehicular particle (<100 nm) number size distributions presented in the literature are mostly averages of long scan-time (~30 s or more) spectra mainly due to the non-availability of commerc...
Aerosol and NOx emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes
NOx emission factors submicron particle size distributions different traffic regimes
2009/1/9
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, Unite...
