Technique for Deterrmining Chloride Content Involved in Each Single Cloud Droplet

[摘要] A halo method (Vittori, 1956) by which one may detect chloride content above 10-13g.was applied to the measurement of chloride content in a single cloud droplet. A transparent film coated with gelatin-gel involving AgN03 was softly contacted upon a residue in a cloud droplet impacted on a Mg0 surface and an induced halo was measured under a phase-contrast microscope.By this method it is possible to observe the chloride content in a droplet with the percentage distribution for each size fraction.
