Meteoric Dust Detection by Light Scattering Techniques

摘要

A careful review and analysis of the present state of knowledge of meteoric influx on the earth indicates that a measurement of the large dust particle concentration (diameter greater than 2 microns) in the upper stratosphere would be highly desirable, especially after a meteor shower. A balloon-borne detection technique is suggested that is similar to that first used by the author to measure the vertical distribution of submicron particles to 30 km altitude. This detection technique would be free of contamination from the balloon and its associated equipment. A laboratory model of the detector that has been developed and tested is described. (Author)
