| Research Abstract |
Techniques for high-precision measurement and automatic data retrieval were developed for the tape-filter type absorption photometer designed by the researcher to measure absorption coefficients of atmospheric aerosol particles. Five systems were installed in monitoring station in Sapporo city to observe the variation of absorption coefficients. They consist of two parts ; those transported from outside of the city and those emitted inside the city mainly from automobile. From the statistical back trajectory analysis it was suggested that absorption coefficients in Sapporo is influenced by the air mass transported from big cities and industrial areas in China and Korea.
