Abstract: A few basic experiments were performed with artificial cloud condensation nuclei and ice-nucleating aerosols in a continuous-flow thermal gradient diffusion chamber to investigate the instrument's response. Brief pulses ...

Abstract: Observational evidence from an Alberta hailstorm was examined in an attempt to demonstrate the link between feeder clouds and hailfalls. Radar data, time resolved surface collections of hail, and cloud photographs from a ...

Abstract: Evidence is presented for a process of ice crystal generation in supercooled orographic clouds in contact with snow-covered mountain surfaces. Comparisons of the crystal concentrations at the surface with aircraft sampling ...

Abstract: A 1.2 m3 continuous slow-expansion cloud chamber was used to simulate natural, liquid cloud formation on soluble cloud condensation nuclei (CCN). Droplet freezing was observed during continued simulated adiabatic ascent ...

Abstract: A ground-based technique is described for determining the liquid water content of supercooled clouds orfog by measuring the mass rate of rime accumulation on a small rotating wire. Development of the techniqueis described, ...

Abstract: wo identical liquid water content (LWC) King probes?one total water content/liquid water content (TWC/LWC) Nevzorov probe and two constant-temperature T probes that are different in size to distinguish particles of different ...

Abstract: Ice formation in ammoniated sulfate and sulfuric acid aerosol particles under upper-tropospheric conditions was studied using a continuous flow thermal diffusion chamber. This technique allowed for particle exposure to ...

Abstract: nteraction of liquid cloud droplets and ice particles with aircraft aerosol inlets can result in the generation of a large number of secondary particles and contaminate aerosol measurements. Recent studies have shown that ...

Abstract: A continuous-flow thermal gradient diffusion chamber was developed for operating in an aircraft and detecting ice nucleating aerosol particles in real time. The chamber volume is the annular space between two vertically ...

Abstract: esign of a new submicron aerosol inlet (SMAI) for airborne sampling of aerosol particles is introduced and its performance characteristics under a range of sampling conditions are presented. Analysis of inlet performance ...
