Abstract
We designed a polar nephelometer with a Xe lamp (500 watts)as light source, and performed the measurements of the scattering functions for the atmospheric aerosol particles near the ground. The scattering functions for the particles under various meteorological conditions were obtained during the period from October 1970 to March 1971. The shapes of the scattering functions obtained were classified into three groups and were compared with the theoretical curves calculated for the size distributions of particles represented by the modified gamma function. The shape of the scattering function measured largely depends on the wind velocity.
Hourly measurements were performed on December 4 to 5,1970and March 8 to 9,1971 and the data obtained show that the shapes of the scattering functions and the scattering coefficients are both dependent on the wind velocity at the time of measurement.
