Interactive comment on “Single-particle characterization of ice-nucleating
This manuscript presents the characterization of individual ice nucleating and ice residual particles using SEM/EDX analysis. The ice nucleating particle and ice particle residuals were collected by three different instruments. This study provides very useful information/insights on the comparison of sampling instruments/techniques for ice nuclei. The subject of the manuscript is suitable for p...
متن کاملInteractive comment on “Single-particle characterization of ice-nucleating
This paper focuses on chemical characterization of ice-nucleating particles and the results from different sampling techniques are compared. The scientific results are in-teresting and the comparison of different techniques is necessary. The results from this paper are an important contribution to the fields of ice nucleation and aerosol chem-istry; however, I can only recommend this paper for ...
متن کاملIce Nucleating Particle Concentrations Increase When Leaves Fall in Autumn
Ice nucleating particles active at −8 ◦C or warmer (INP−8) are produced by plants and by microorganisms living from and on them. Laboratory studies have shown that large numbers of INP−8 are produced by decaying leaves. At three widely dispersed locations in Northwestern Eurasia, we saw, from an analysis of PM10 filter samples, that seasonal median concentrations of INP−8 in the boundary layer ...
متن کاملSingle-particle Characterization of Ice-nucleating Particles and Ice Particle Residuals Sampled by Three Different Techniques , Björn Nillius
In the present work, three different techniques to separate ice-nucleating particles (INP) as well as ice particle residuals (IPR) from non-ice-active particles are compared. The Ice Selective Inlet (ISI) and the Ice Counterflow Virtual Impactor (Ice-CVI) sample ice particles from mixed-phase clouds and allow after evaporation in the instrument for the analysis of the residuals. The Fast Ice Nu...
متن کاملPerformance of a quarter-wavelength particle concentrator.
A series of devices have been investigated which use acoustic radiation forces to concentrate micron sized particles. These multi-layered resonators use a quarter-wavelength resonance in order to position an acoustic pressure node close to the top surface of a fluid layer such that particles migrate towards this surface. As flow-through devices, it is then possible to collect a concentrate of p...
