Correlation of Chloride Particle Abundance with the Synoptic Situation on a Cross-Country Flight

Abstract
An account is given of the collection of airborne chloride particles, by airplane, on a cross country flight. The accompanying meteorological situation is described. The distribution of chloride particles found is consistent with the view that they originated in the Gulf of Mexico and in the Pacific off the coast of Mexico. The greatest abundance of chloride particles was found east of the mountains in southern California, in air that probably came from the region of a tropical storm.
