The polar nephelometer of Tohoku University has been improved so that it can be used to measure the scattering matrix element <i>D</i><sub>21</sub>. Polar nephelometer observations were conducted at Tohoku University in the suburbs of Sendai, Japan, from 12 October to 10 December 1988. A method presented in an earlier publication [Appl. Opt. <b>36,</b> 7992 (1997)] is applied to determine the complex index of refraction and size distribution of aerosols simultaneously. It is shown that the accuracy of the determined quantities is reasonable.
