water cloud droplet size distributions backscatter glory Remote sensing
2009/3/3
Cloud single scattering properties are mainly determined by the effective radius of the droplet size distribution. There are only few exceptions where the shape of the size distribution affects the op...
Aerosol number size distributions have been measured since 5 May 1997 in Helsinki, Finland. The presented aerosol data represents size distributions within the particle diameter size range 8-400nm dur...
An inverse modeling procedure to determine particle growth and nucleation rates from measured aerosol size distributions
inverse modeling procedure nucleation rates aerosol size distributions
2009/1/13
Classical nucleation theory is unable to explain the ubiquity of nucleation events observed in the atmosphere. This shows a need for an empirical determination of the nucleation rate. Here we present ...
