Abstract
Abstract A system for automatically sampling fog-water at a known rate, for determng the electrical conductivity, and for retaining fog-water samples for additional related study. The conductivity of the collected water is used to estimate total salt content of the fog and/or air, which determines the availability of salts to act as the condensation nuclei for fog and haze.
