Cloud and precipitation physics research 1983–1986
TL;DR: This paper pointed out that many microphysical mechanisms are not understood in quantitative detail, and it is now evident that the solution to many of the outstanding problems in atmospheric science will require an understanding of processes within the scope of cloud and precipitation physics.

Aerosol over the Southern Ocean
TL;DR: In this article, the authors assess a proposed climate change feedback process involving cloud condensation nuclei (CCN) and cloud albedo, and assess CCN concentrations N as a function of supersaturation S were measured on a voyage from latitude 43 to 65°S in October-November 1988.

Nucleation scavenging of submicrometer aerosol particles
TL;DR: In this article, the efficiency of nucleation scavenging of submicrometric aerosol particles with radii between 0.028 and 0.28 μm was measured at Tsukuba, Japan, during the summer and winter of 1987 by using two thermal gradient diffusion chambers, with and without a water vapor source.

TL;DR: In this article, the authors describe the status of their efforts to develop the instrumentation to collect cloud condensation nuclei (CCN) in amounts sufficient for chemical analysis, and a statistical model of the operation of the system is presented to show the ability of a system to collect CCN in two different size ranges for which they plan to determine the chemical composition.

An Automatic Light Scattering CCN Counter
G. Garland Lala,James E. Jiusto +1 more
TL;DR: An automatic instrument for the measurement of cloud condensation nucleus (CCN) concentrations utilizing a thermal gradient diffusion chamber and light scattering has been developed in this article, where the concentration of droplets (activated CCN) in an illuminated volume is determined by measurement of the peak light intensity scattered at 45°.
